Do you have spark? jim i have tons of spark, if i hold a rag full of gas in front of air intake it fires right up > jim > i have tons of spark, if i hold a rag full of gas in front of air > intake it fires right up Then you can't have fuel pressure. There might be an inertia switch that shuts off the fuel pump in case of an accident. Look in your owner's manual. They usually have a reset switch somewhere. Airbags have nothing to do with that problem... how did you determine the injectors are not working? Professor Check out FlashAlert at www.telstar-electronics.com i used a noid light > i used a noid light If you have fuel pressure, the injectors are firing, and spark, then check the cam timing. Maybe the belt slipped in the collision. Does it sound normal turning over? jim first thanks for the help. i installed pressure guage between filter & fuel rail. ihave 42 pounds& can hear pump running.the thing is that when i do the rag thing it runs perfect till it runs out.i used a stethascope and cant hear the injectors clicking thanks "MERLIN" > jim > first thanks for the help. i installed pressure guage between filter & > fuel rail. ihave 42 pounds& can hear pump running.the thing is that when i > do the rag thing it runs perfect till it runs out.i used a stethascope and > cant hear the injectors clicking > thanks "MERLIN" Doesn't make sense. If you have fuel pressure and the injectors are firing and it runs off the rag, it should run... thats just it the injectors are not firing > thats just it the injectors are not firing Oh, sorry, I misread your earlier message. I thought you said the noid light showed they were firing. Guess I don't know then. I'd have to troubleshoot it. I'd say crank sensor, but since the plugs fire that's probably not it. Could be a bad ECU or damaged harness. Do you have an OBDII scanner? You might want to see if any codes are set. -jim i was thinking the same about crank sensor. the book says the sensor controls the injector paulse. i think its worth a shot. thanks for all your help. MERLIN i got this thing from a friend .his wife ran into the back of someone and popped the bags.he went to the seen,started it ,ran perfect all the way home,shut it off and has not started since!this thing is driving me crazy! i got it!!!!! it was the ground on the eccs relay.i want to thank jim v for all his help.thanks jim!
