93 4.3cpi 2wheel wont start
i have been all over this vehicle.new fuel pump,filter,lines going into plenum,spider{fuel pressure reg,injectors}plugs,everything!it will not start.i unpluged the new fuel pressure reg to make sure gas was getting to it,turn the key,plenty of fuel.put it back together,wont fire{i have spark thats all new too}.took a spark plug out to see if the injectors were spraying,crank the key,nothing but air.weeks i have been trying to figure this out.any ideas anyone?gas tank is new also.[:@] [:@]
I have seen a few different people have problems with the electrical lines/connections inside the plenum not properly activating the injector. You may want to see if that is the cause.
Have you checked the timing. It could have jumped time and it will never start. Bring the number 1 piston to TDC, Check that the rotor is pointing to the number 1 plug. The Rotor should be pretty close to the # 1 wire location at the distributer cap.
Are injectors pulsing, I do believe you can check the Injectorpulse with a Noid light. (At least that's my understanding of a NOID Light) That would tell you if the injectors are being controlled by the computer.
i took back spider{fuel pressure reg,injectors}and got a new one just to be sure.same thing.i have fuel pressure.with the plenum off i can see the gas through the line,it makes it all the way to the spider fine.but when i hit the key,no fuel sprays out of the injectors at all.i have twelve volts to the spider as soon as i hit the key.im gonna go check the conecting clip real good,thats a good idea swart .ill be back.
