Had the same problem on my 94 Rodeo. I checked the fuel system, changed filter, fuel pressure regulator, disassembled throttle body and thoroughly cleaned it and nothing. It would act like it wanterd to start but wouldnt. Funny thing though, in the morning it would start fine, idle for a couple of minutes and then die. Well, turned out its the "Mass air flow sensor". Located on the top side of the breather tube by the air filter. Easy replacement, painful on the wallet.
It sounds like you have a break in the wire which connects your alternator to your battery, get it checked out.
This is not a battery problem. Your charging system, the alternator, is not putting out enough juice to charge the battery until you reach 4000 rpm. Have the alternator and charging system checked.
Remove the starter and haeit checked at auto parts for amp draw Check the alternator to see if it is keeping the battery charged Check engine ignition timing may be too far advanced
You will have to have the code checked to know why.
The alternator is not charging the battery, therefore, the coil is getting it's charge only from the battery.
have you checked the battery output? it should show right at 13.4 volts, if not, check your alternator output.
yes your battery may be duff, however it would be worth getting your charge rate checked by a garage as the problem can also mean an alternator problem
make sure the small wire is hook to the post
If the engine doesn't turn over at all there are a few things that are possible. Start with the battery ground cable and make sure it is making a good ground and is not broken. Also check the positive cable from the battery to make sure you have a good connection and no breaks in the wire. If these are both good you may need to replace the starter motor. There are brushes inside the starter (yes they can be replaced if you know how to take the starter apart) that will grind down to the point of not making enough contact to start your car. Since you said you had the alternator replaced I'm thinking it probably is the starter because any competent mechanic would have checked the battery cables before replacing the alternator.
See if the pipes are broken or rusted. That's what happened to my well, and it started pumping mud.
Possibly harmonic balancer or pully. I replaced battery, checked alt. and other parts. Was told it was fly wheel, but mine is automatic, doesn't have one! It has a flex plate.
Battery is dead?
