ive exhausted my resources.no fuel to the cylinders,but fuel up to the rail with good pressure.have replaced pressure regulator,TFI module,fuel filter,fuel pump,injector harness,and computer,also bypassed the inertia switch.checked voltage at injector harness(good),checked ground at motor from computer to injector harness(good).can hear relays and pump kick on and off with key.what else could i possibly check?why arent my injectors firing.plugs are bone dry after cranking.even took tfi module off and had the new one tested(good).

 

Are they even spraying? Apply voltage to them and see if they spray. fuel pump relay under seat is ok? I also cant understand why everything is ok, and you even have voltage to the injectors but no fuel to them. Something isnt sending fuel to the injectors. getting any kinda codes?

 

i havent checked to see if they are spraying,i do have the proper voltage to them though.im getting code 41 and 91,but i thought that seemed like it had nothing to do with the problem i was having.that is for the hego sensors.that was the last time i got it to fire up,which was about 5 days ago.now it just cranks.before it would start up and when you shut it off it would not start back up.did that for about a week,now just cranks.

 

Well the heater Oxygen sensors might have set a code because it was running lean... maybe the injectors are not firing

 

maybe my tps is in wot mode,how do i tune that sensor in?

 

Your computer is bad. The computer controls the ground side of the injectors to make them fire. You may have good Fuel press. and injector voltage but thge computer isn't firing the injectors. A used puter is around 60 greens.

 

ive replaced it with a remanned computer and it did not fix it

 

If you havent yet, hook up a noid light to one of the injectors. That will tell you if the injectors are firing at all.

 

ill pick one up today and try that,thanks

 

throw a carbie on there
