Being that this is a carbed engine, i would think it has a mechanical fuel pump and not a electric one right?
If it is a mechanical one a fuel pressure tester is pretty cheap for that(I bought my lower pressure fuel tester for like $20 bucks).
Sears has them and harbor freight has a pretty nice set for pretty cheap.Like Eric said, you never know what your getting into when the vehicle has modifications.
I would start by hooking the fans directly up to the battery with with a relay and switch
Just flick them on when you start the vehicle.[quote]Quoted From Trcustoms719:
I would try pressure bleeding the system.
Heres how:[ul]
[*]Attach the pressure bleeding equipment to the Master Cylinder.
[*]Attach a clear plastic hose to the bleeder screw and feed the hose into a clear jar containing enough fresh brake fluid to submerge the end of the hose.
[*]Open the bleeder screw at least one full turn or more to obtain a steady stream of brake fluid.
[*]After approximately 4“getting fuel” Did you use a fuel pressure tester?
Just cause it’s getting fuel to the engine does not mean it has enough pressure.
Did you check out the cap and rotor yet?
Is the rotor spinning freely when the engine is cranked over?I hold a little pressure on it while i tighten them, so when the bolt is turning it does not release any of the tension.
Quoted From blinkskaterkc:
Usually you can bring it to a shop and most well-known places will pull the CEL code for free. Or you can invest in a scan tool and do it yourself.
A bad O2 sensor may be to blame I suppose. I’m not sure why the car would shut off, but I guess if you had a bad O2 sensor, then that could be why you felt the jerking. It may be giving false readings to the computer and therefore creating a sudden lean or rich mixture.
I guess it is possible that the O2 sensor could cause it to do that.
It might be switching to full rich or lean real quick and that is causing the engine to cut out.I agree with bigc, this car might have a bypass valve for the heater core.
The heater core might have air in it and when you turn on the heat it lets the air through and into the rest of the cooling system.
Let me look into the bypass valve thing and I’ll get back to you.Ok, It doesn’t look like it has a bypass valve.
I would see if the heater core is blocked, A new one is like $32 bucks at autozone for your car.I still don’t see how turning on the heat can cause the engine to over heat.
