PVC simply recycles the blow by gases. You have either blown a fuse, or your fuel pump is not delivering gas to the motor.

ok, well as for the relay, yes there is one in your under hood fuse box....or inside the drivers door...but if you don't hear the pump, fear the worst, it may be dead.....happens ALOT.....check and change the relay, about $10, then if nothing, time for a new pump.

SOURCE: code po100 & p0300 come

P0100 is mass airflow circuit, p0300 is multiple cylinder misfire. Faulty maf sensor is most likely the cause of the misfires.

1988 chevy S10 turns over but won't start getting spark put in new fuel pump,cpu and injector. If I pour A little gas in throttle body hole it will fire for a few sec. fueses all test good.


Hello, just had this problem myself. Check your EGR valve by pulling the vacume line off and pushing up under the valve put your finger over the vacume line hole and release the valve, if it returns to normal position then its bad if not its good. If its bad it needs replaced. Mine did the exact same thing and thats what it was. Hope this helps

1998 Grand Marquis. Start goods. idols low. put in gear, stalls out. Changed fuel filter & had injectors serviced. Problem remains. Could it be the Transmission modulator valve?


I would check the operation of the idle speed control valve, it is what changes the idle speed when a load like the transmission is put on the engine, without it the engine will idle slow and stall out, this is even more apparent when reverse gear is selected or drive or the AC is tuned on. The ISC valve is located on the side of the throttle body top of upper intake manifold. Below is a picture of the ISC (idle speed control valve)

Van dies after 10 min drive when pulling into


Try removing the idle speed motor on side of throttle body, and spray it clean, as well as the port it came out of, with throttle body spray cleaner. Don't pull and extend shaft of idle motor, just leave it in position it's in, and make sure you don't lose small "O" ring on idle motor. Re-install and try it. If it cures it for a while, then starts to do it again, replace the idle speed motor.

Follow the intake tube from the air box to the throttle body. It is mounted on the throttle body, on the opposite side of the throttle cable.

Idleing problems


Hello,it sounds to me that you have a vacume leak.Check a vacume tube that is under the throttle body right in the middle of the firewall and the intake manifold.This vacume tube has a rubber elbow shaped connector at the end of it on the engine side.They regularly fail.
