PRESSURE WASHED UNDER HOOD... HASN'T STARTED SINCE..TOOK TO MACANIC HE SAID FUEL PUMP IS GOOD IT MUST BE THE COMPUTER ,ANOTHER ONE SAID IT IS THE DISTRIBUTOR ..CAN YOU PLEASE TELL ME WHAT'S WRONG WITH MY CAR
SOURCE: 1990 montero no start. No power to open injectors, good fuel pump
The only other thing to try would be to use a continuity tester with noise and back trace to the computer or get computer wire color code to test injector pulse at the source.You may have a broken or poor wire that you cant see or a plug thats not in properly etc.

electronic engine control unit calculates the mass of fuel to inject, not how wide it sprays. It's the type of solenoid that you use. Some have wider spray nzzles than others. An external Fuel pump helps the delivery of the fuel. Also since fuel injectors rely on mass air flows nowadays, you have to have proper mixture coming through. hows your Fuel pressure regulator?
The throttle position sensor reports to the computer the position of the throttle butterfly valve, which the ECM uses to calculate the load upon the engine-but inorder for this to run, you may need an external pump.
Sounds like nothing is being grounded back to the ECM to even give a reading. If your regulator is improper and you do not have a external pump (depending on your model), than check those. If not, Start from scratch.
If you ever lose your way, go back to the beginning_REWIRE!
Goodluck.

Do you hear the fuel pump buzz for a few seconds when you turn on the key? If not you have an electrical problem. If you do, then trace the fuel line from the tank to the first point where it connects to something and loosen the connection. Turn the key on and see if you get fuel. If not then the problem is between there and the tank. If you do then try other end . Keep doing this at every junction and you should find the cause of your problem. Hope this helps.

Hello! Please tell me what you meant by "We took the wires to check for mass"?
However, you are correct, it is fuse #5 10amp. It is located in the under hood fuse block. Change the fuse; If it does not hold perform the following test...
With key off...Disconnect the Injector's plug in connectors...Each connector has two wires marked A and B...A goes to battery feed and B to the Power Train Control Module (PCM)...
Using an ohm meter set on the X10 scale measure from each plugs pin A to ground...It must be open, no needle deflection...If you read any resistance at all, the hot lead which is common to all injectors, is grounded in the harness...
Next measure from each injector (both pins) to ground...You should read zero ohms,,,No resistance to ground...If any one injector reads to ground it is defective...Replace...Since all injectors are tied to common battery, any one injector shorted to ground will short all of them to ground...
