After clean gas and a new battery started up and ran with no problems for a week. Started to run ruff, then quit all together. Would fire with either down the carb. Tried a good ing. coil. didn't start. tried ing module, didn't start. Tried a working ECM, didn't start. Haven't checked the injector pulse with a noid light but I haven't seen any fuel from come out of them. No 12 volts from the pulse wires. No light with a test light. I'm sure I don't have an injector pulse. what do I need to do next?

You need to test both fuel pressure and injector pulse. If you find no pulse, check for power at one side of the injector with the key on. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. ftoons New User Apr 24, 2011, 10:05 AM Post #3 of 4 (2769 views) Re: No injector pules 1994 G20 Van 5.7 Sign In Still try'n to find a noid light. Have power to positive two wire splice at injector pulse wire when key is turned on. Haven't located a a fuel PSI gauge. do you know what the pressures should be? Read somewhere it should about 60 in 56 out. Checked the grounds to PCM, A1, A2, A12. Found no problems there. Still trying to find the ground for the fuel pump relay?

The spec is 9 to 13 PSI You can get a noid light at most any of the large chain parts stores for under $10 so you still need to do that unles you find no fuel pressure. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
