front injectors not firing

hhn2002 · 11-13-2008, 10:39 PM

i noticed a while back when i had my intake manifold off that there was a fuel film on my rear intake runner but not on my front runner right after the secondaries. i let my car sit for a week, then tried to start it and it didnt start. no big surprise there, but when i crank the engine to de-flood it and i pull the plugs only the rear spark plug had fuel all over it but the front was bone dry. what does that mean when both my sec and pri on my front rotor dont spray? btw my car is a 91 vert. could it be the ecu?

thanks in advance

check the injector wiring, could be a problem with the ecu but not likely.

you might need to send your injectors off to be cleaned.

bad injectors as in not functioning and i need new ones or as in they're dirty and need to be cleaned?

Unfortunatly you wont know that until u have them clean and flow tested..

MOST places do this for under 20.00 an injector..

Check out KGParts. he is a vendor here and I have heard good things about his work.
