Car Starting Problems

on the passenger side of the car on engine bolted to the flywheel cover /bellhousing access underneath on truck raised on jackstands don't know what your doing have right tools take it to shop approx cost varies area 325.00

Disconnect the battery, remove all spark plugs, and turn it over with a socket at the crankshaft.

If it's the ignition your vehicles motor will not turn over at all. If it does turn over it's either one of three things: battery, alternator, or starter. You can take your starter, battery and alternator to a local advance auto parts and they will test the charge for you. That will tell you what you need to know.

In a situation like that I always tell people to go back to the basics: Spark, fuel and Compression. If you have all three, it should start. The spark has to be at the correct timing, but if the vehicle was running and suddenly stopped, there isn't much reason to believe that the timing changed. The fuel has to be delivered in an approximately correct quantity for the engine to run right but it should at least pop and attempt to start. So... Start with fuel. Using starting fluid, spray in the throat of the throttle body while a friend attempts to start the engine. If the engine runs while you're spraying, you probably have a fuel problem. Check the fuel line for pressure. If you don't have any it's probably the fuel pump. It's in the tank and you'll have to drop the tank in a suburban to get to the fuel pump. It isn't as bad as it sounds. Disconnect the battery first. Siphon out as much as you can get easily, disconnect the fuel fill pipe from the tank, using a floor jack, support the tank while you remove the straps. There are usually only two. Once the straps are disconnected, lower the tank and remove the fuel line and the wires to operate the fuel pump and fuel gague. You'll have to clean the top of the tank so that you don't get debris inside, then remove the screws and work the pump assembly out of the tank. On the other hand... if you have fuel pressure and the engine doesn't start when you use the starter fluid, you probably have a problem with ignition. Pull one spark plug wire, then using a spare plug from some other source, attach the wire to the spare plug and lay the plug on a metal part of the engine, then crank the engine and watch the plug. If you have spark it might be something else. If there is no spark, find out why. It could be the pickup coil, electronic ignition module, high voltage coil or even a bad rotor in the distributor. It's all a process of elimination. Remember the words of Sherlock Holms, "When all other possibiliities have been eliminated..."

First of all you have to get up there, you might need a ladder or chair or something. Once your up there jist jump off, try to land on your feet.

Could be a fuel system problem. First thing is to replace the fuel filter and then have the a fuel pressure check done. Also some electrical parts will fail after they get hot. An engine requires 3 things to run. Fuel, air, spark. Find out which of these you do not have when it will not start.

Try to wiggle the wheel a bit and trying again.

very very low on fuel or faulty fuel pump

If you have connected the battery backward and seen smoke from the drivers foot well you have melted some all of the relays/ cables electrical components of you vehicle, first you will need to remove all of the covers and trims in this area and start checking for signs of heat damage/ burning and other damage to the components in this area, It sounds like the cables to the ignition switch have been damaged and there could be some blown fuses.

Also the reverse polarity that occurs when this is done damages the diode pack in the alternator this is the unit the converts the AC current in to DC so that it can be stored in the battery.

Could be a costly mistake.

Haven't heard of vapor lock with electronic fuel injection. That was a problem when vehicles had a carburetor. What seems to be the problem with your vehicle?

Look in the owners manual for the fuel shut off reset. The fuel shut off is for accidents and limits fire hazard.

I'm sorry, but I don't have access to real-time data or specific metrics about external websites or platforms, including "wcwx3." You may need to check the relevant analytics or reporting tools associated with that site for accurate information.

Remove the serpentine belt , runs alt , AC and such try to start if starts, and probly will, check to see which pulley or unit is seized up Alt AC water pump

The VT Commodore might turn over a few times and then start if there are teeth missing on the flywheel. The starter wires might also be shorting out or loose.

It has nothing to do with oil pressure. You probably are starving for fuel at startup. Possibly a defective fuel pressure regulator, clogged fuel filter, or a weak fuel pump. Try turning the key on and waiting for around 10 seconds before starting. I would replace the fuel filter before going any farther.

If the switch is properly bypassed, then yes.

I just replaced one 4/23/08 on a 2000 trooper with 4wd-auto tranny. Service manual says to remove exhaust pipe and sensors to make room. I didn't want to mess with busted studs and rusty bolts. Saw a guy post on here that (on a rodeo/passport), after removing the mounting bolts he took the starter apart and removed it in three pieces. Then reinstalled it the same way. IT WORKS !! After disconnecting the battery and removing pos wire and clip on the solenoid, remove solenoid slide it out., Then remove starter motor from base, slide it out, followed by the base. After testing to see what was wrong with it. Practice taking the old one apart and putting it together a few times to get familiar with orientation. When you're ready to install the new starter, have it apart and put tape(NOT TOO MUCH) on the starter motor to hold the gearing and long screws intact while installing. May want to mark base and motor assy with fingernail polish to see them line up easier while lying on your back. Put base cap in first,followed by motor(try holding upward so gears don't try to fall out(TAPE). Get a few turns on the long screws and remove the tapeI used needle nosed pliers), then tighten all the way making sure shift lever is centered. While putting the solenoid on make sure it meshes with the shift lever before tightening . BE PATIENT>Go ahead and hook up the starter wire to the solenoid, then starter wire clip and the pos battery cable. You can now mount the whole assembly as one. CHECK FROM TIME TO TIME THAT SMALL RUBBER DRAIN HOSE ON UNDERSIDE OF STARTER HASN'T been knocked off. You'll need 14mm socket and extension and universal for the starter mount bolts. 8mm, and 10mm nut driver for starter and solenoid removel/install from base. 12mm wrench for pos wire and starter to solenoid wire. Torque for for starter to engine=30ft.lb solenoid to base=41 in.lb starter to base=48 in.lb Should'NT take but a few hours to do the whole job with a break or two in between.

Got the rebuilt starter w/lifetime warranty for $115 from autozone. good luck

p.s. When removing starter motor from base DON'T mess with the two small Phillips screws. Just the two long bolts 8mm.

If the car overheated, you may have warped the aluminum head. You may have to have the head shaved and a new head gasket put in.

The 1994 Pontiac Grand Prix gear selector wire can be found beneath the center console. The gear selector wire will go to the instrument panel.

If it is fuel injected. It is likely the computer, that run the fuel injection system. This is located behind the glove box.

no this is not a computer problem.it is either a starter motor problem or the ring gear on flywheel is worn

no fuel getting to engine

firstly you need to buy a bypass tool from supercheap auto. Then all you need to do is plug it in to the immobiliser, press go and you're done.

Probably wore out ignition key or switch or needs lubrication.
