I need some help please. I have tried everything I can thin of and I need some other input.
Alright, from the top..my buddie has a 91 std hatch that he swapped a b16a into it. It ran fine prior to the swap. he wanted me to do the wiring. I left it OBD0, did the dpfi to mpfi comversion...(everywhere i read, it said that pins B10 and B12 are supposed to be empty, but b10 had a white/red wire in it..I cut B10 wire and ran it to the disrtibutor), wired the obd0 b16 distributor to his old plug and added the crank angle sensor wires. All he has for an ecu at the moment is a pr4(obd0 ls ecu). I got every thing ready to test start, and there was no fuel pressure. I turned it over and there was no spark but the coil had 12.4x volts. coil also had proper ohms. I hooked my noid light to the injector and got no pulse. I checked all the grounds and they are good. The main relay was not cliking when i turned the key but it has constant 12v. I jumped 12v to the trigger wire on the relay, it clicked, and BAM! I got spark. Sprayed some gas in the intake, turned the engine over and she runs as long as i keep power on the relay and spray gas in the intake, but sill no fuel pressure nor anything from my injector noid light. It's like the ecu isn't getting power or ground. I swapped the the main relay and rechecked all the fuses but same thing...no fuel pressure, no injector pulse, no spark unless I jump power to the main relay. His tps is getting 1.xx volts on the power wire!?! I'm banging my head and this guy needs a car yesterday.
Any ideas?
thanks a bunch...Taylor
