I just replaced a valve spring, i also thought it would be a good idea to change the head gaskets-as well... so i put 'er all back together and now--there is NO GAS spraying out of the 2 TBI INJECTORS. So it wont fire-up!! There is gas going all the way to the TBI unit in the lines,but it just will not come through the injectors when i turn it over... The (new)injectors only have around 1 years worth of use too!!! I changed the fuel filter,and the fuel pump is energizing and seems to have enough pressure. The FP fuse by the battery is good,as all the other fuses are. There are no codes stored in the ECM either.
Boy i am stumped, and i need help with this one. thanks, Brad.

ARE ALL THE IGNITION WIRES ON THE BACK OF YOUR DISTRIBUTOR PLUGGED IN? CHECK YOUR IGNITION CONTROL MODUL AND YOUR IGNITION COIL. IF YOUR SPARK PLUGS ARE NOT FIRING THE ECU WILL NOT LET YOUR FUEL INJECTORS FIRE.

WELLS C846 $17.99 (AUTO ZONE)

 

Yep, All the wires in back of the distributor are good-n-tight, i even put a (new ign.module) on under the dist.--still no luck. I did however get a nice ball of flame from cranking her over-probably from spraying starter fluid-in vain ...lol....but, all fuses are in good shape, and still no codes.

Could it be a possible ECM issue? I mean it ran just fine, before i replaced the valve spring and head gaskets. Im at a temporary loss of ideas...HELP LOL===Brad.

 

DO YOU HAVE A NOID LIGHT (TBI FUEL INJECTOR TEST LIGHT)

IF SO HAVE YOU TESTED IF THE ECU IS FIRING THE INJECTOR

IT'S ABOUT $5.00 A AUTO ZONE

IF IT'S NOT CHECK YOUR ESC MODULE (ELECTRONIC SPARK CONTROL MODULE)

WELLS ESC105 $52.99 (AUTO ZONE)

 

Hi, would it have to particularily have to be a (TBI FUEL INJECTOR TEST LIGHT) or would a standard test light work? Hmmm... Im surprised that it could be the actual injectors, i mean i did replace them about ooooh maybe 30k ago, i bought them from TPIS. I will investigate the ESC tomorrow though.===thanks man, Brad.

 

UNLIKELY THAT BOTH INJECTORS WOULD GO AT THE SAME TIME.
