It could be the timing belt jumps (wrong timing spark) or the faulty pressure regulator (to much fuel ro to little)
bad spark plugs, or coil. how many miles? also, when trying to start, have someone tap on the gas tank with a hammer.
Sounds like either a weak battery (bad cable corroded) or starter solenoid needs to be replaced
If it has spark & fuel and will not start then the timing may be off.
the ignitor is bad
It has fuel or spark problems. Next time it doesn't start check for spark. If it has good spark it must be a fuel issue. Maybe a failing fuel pump. Try spraying a little starting fluid down into the throttle body and try to start it. If you get some response you probably have a fuel problem.
If you are getting fuel and it will not start you have no spark.
Without fuel and the lack of spark, you can crank the engine continuously for the next 5 years and it will never start. One needs to find out why there is no spark or fuel. Start with the fuel pump and check the fuse(s), and then check the operation of the fuel pump. Check the electrical system of the car - check fuses, check wiring.
Have you checked for fuel and spark? Fuel pumps ad burnt ignition rotors are very commen on these vehicles
I hear that the problem is the pressure to the fuel pump. Also have heard that the alternator is the problem. To be honest, I cannot figure out why mine will not start either. I have replaced the fuel filter, O2 sensors, thermostat, reset the inertia switch, and spark plugs and wires.... nothing has worked yet. I have had the same problem, 2cd Explorer. I replaced the fuel relay. No problems now
If it does not start it is missing either spark, fuel under the proper pressure , compression or the timing of the ignition or the camshafts are incorrect. Start by determining what is present, check for spark, proper fuel pressure, engine compression.
Does it turn over? yes Does it have spark? yes Does it have fuel?yes
Fuel, and spark. Check for these first.
Check fuel pressure. It may be the fuel pump, located in the tank.
Does it turn over? Does it have spark? Does it have fuel?
There are multiple electrical and mechanical causes to a no start condition. No fuel pressurization and spark may indicate a fuse or electrical fault, as opposed to a starting system problem alone.
You need three things for the engine to run, compression, fuel and spark. You say you have fuel now check for spark.
It isprobably not getting fuel or not getting spark.
check if you have fuel and spark it needs both to work
u
Does it turn over? Check for fuel and spark--could be bad fuel pump or bad ignition coil
did you have a hot spark when you tested for spark ? i did you test the fuel pump pressure ? did you cheak for pulse on the coil to see if you were getting a signal ? i have spark, gas, the fuel pump works great and the coil is getting plenty of signal but it still wont start What was the fuel presure reading ?
