Check the hot wire going to/at the distributor .. a number of these were crimped on the wires insulation/casing and not on the wire itself,,, it makes intermittent connection.
..This is hard to diagnose,, your symptoms are exactly what this causes... Good luck...

SOURCE: 1999 Chevy S10 cranks but wont start

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech

SOURCE: 2001 chevy silverado 1500 v8 battery drain after sits for 1or2day

, do a simple test on the charging system...check battery voltage. should be 12v or better. start engine & check volts at idle, no accessories on. volts should read 13.5 -14v. Turn on all accessories(including headlamps on high) volts should drop slightly but should not creep down. Definitely not below 12.5. If voltage drops lower than 12.5, the regulator (in the alternator) is not working. either change regulator or change entire alternator. Alternator drive belt should have sufficient tension so that alternator cannot be turned easily by hand. If it can, check belt tensioner.

SOURCE: I replaced my starter for a 98 chevy suburban 2

Possible not shimmed correctly. The starter teeth have to engage correctly for the starter not to hang up. That's what probably happened & broke teeth off. You had better check your flywheel around the entire circumfrence as teeth may be missing from it as well. Starter won't engage if teeth and flywheel teeth in same spot are broken off. If the flywheel teeth are bad, it will be a spendy fix to put a new one on... Rick

SOURCE: 1997 chev 1500 with 350 vortec milky oil in dipstick tube

Sorry to say its your head gaskets. Probably from the overheating it wore out the gaskets. that milky stuff is your coolant mixing with your oil. Good luck. Suggest you take it to a pro. the gaskets are easy to change, it's everything else in the way to get to them that requires special tools and experience. Let me know how it goes. I have the same thing with my truck but not real bad. If your truck is running smooth and doesn't feel like its missing, or when your start it no puff of white smoke comes out your exhaust it's not that big of problem. if these are happening then i would get a quote.

Our fuel pump stopped working on our 98 Chevy Blazer V6 4.3L Vortec Engine, so we bought a new one. A couple days later (before replacing the fuel pump) it started up and ran but ran crappy. So we did


what did you do (replace it) if you still have a miss you may need to tune it up / make sure the fuel pump you bought is for the right psi for your blazer

1996 chevy 3500 7.4 vortec. the ecm fuse blows at the turn of a key


One of the power wire going from your ecm to a sensor or solenoid is shorting to ground. Get a wiring diagram and an ohm meter. disconnect the battery and start checking each wire measuring from the wire to ground. as you wiggle you will see the meter show 0 ohms when it is shorted. These are the hardest and most time consuming kind of electrical problems .good luck

Just purchased a 2002 Nissan Sentra and 3-5 days later the car began shutting off when stopped on several occasions and starting back up. Lastly the car shut off while in park and would not start up again...


Next time it does it. try hitting the fuel tank. a couple times if necessary. if it starts back then your fuel pump is dieing. some times when the pump heats up they will stop working, only to come on latter. let me know

I need the torque specs and sequence on a 1998 chevy 350 vortec


Vortecs are a little different that old school small blocks, grab a Haynes or Chiltons, the cross patterns and specs are simply diagramed. Vortec, as any really, start with 25# then 45# and then final torque which I believe is around 70-75# but to be sure verify with the manual. AutoZones, Murry's, Adavance auto all carry the books, Cheap insurance.
