check for spark if there is no fuel coming out of injectors you can borrow noid lights from orielies auto parts check the injectors for pulse width if you have no pulse your computer is bad if vyou have no spark remove dist ributer cap and see if rotor turns while cranking if it does check for spark between coil and dist if no spark you more then likely have a bad ignition module
Must be a fuel problem, since you are getting spark. Can you hear the pump turn on when you turn the key to on? I would check the injector circuit, and if it is working, have the fuel pressure checked-might be too low from a weak or tired pump.
The injectors have a hot wire to them-always hot with key in on position. There's also a fuse for the injectors, as well as a fuse for the fuel pump. The ground wire from injectors goes into the engine computer so it can control injector pulse. A tester called a "noid light" can be used to check the injector circuit. Just plug it into the injector connector and crank the engine over. If the noid light is blinking, the circuit is working right.
did you check the fuel pressure pump on the frame rail for power and ground? have you verified no ignition spark to the spark plugs? have you checked for fire from the coil to the distributor cap? does the check engine light come on when you turn the key on? have you check for injector pulse and power at the fuel injectors? if the fuel pump won't come on and you have no ignition fire and no injector pulse, all of these systems are triggered by the ECM.
Check all fuses first. Then have someone listen near the back wheel when you first turn the key to "on" they should hear a hum if the fuel pump is working. If not, you will need a pressure tester for the fuel system to check for pressure at the test port near the engine. If OK, check for spark and injector pulse (you'll need noid lights for the injectors). If fuel pressure is low or none, you need a pump (don't replace till you check to see if it's getting power). If no spark or injector pulse, you probably need a Crank Position Sensor.
you need to see if you have spark and check all fuses and see if you have fuel pressure and injector pulse if no spark and no injector pulse suspect crank sensor or ignition control module if no fuel pressure check fuses then relays and then suspect pump
Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.
