Have you checked the fuel pressure? There is a test port on the fuel rail (looks like a valve stem) you can use a small screwdriver to depress the valve and fuel should come out (be carefull it will be under pressure, make sure that there is no hot items close) ever if fuel does come out you may still need a pump if the pressure isn't high enough.

1998 mitsubishi mirage winding over but won't start I have plenty of spark at plugs I have fuel at the fuel rail .I have power at injectors .should power at injectors pulse when cranking ?


Injectors fire when grounded. The power should be constant.

However, if its not turning over and just cranking, make sure your injectors and plugs are connected to the right cylinder. Also, check your plugs for moisture after cranking. If the plugs are wet, then that cylinder isn't firing. If they are dry and hot, maybe they aren't getting any fuel. Has the car sat for a while? When was the last time it started?

Car wont start. took a fuel injector out and put the same one right back in and it ran for 2 days fine now wont start again, what is the problem?


A possible fuel pump pressure issue. You will need to have a garage check the fuel line pressure. The engine requires more fuel on cold start and a failing pump may not be able to cope with supply. This may also be apparent at high revs, but not as apparent as cold start.

1986 Corolla GT-S Fuel Injectors Not Firing


Here's how to check the injector circuit.
Pull off one injector connector and with a testlight grounded on the engine, turn key to on. Probe the terminals of the injector connector. One of the terminals should have steady power from the ignition being on. If neither terminal turns on the testlight, the injector drive circuit is not working. There may be a fuse for the injectors out. Also check the efi fuse, located I think under the hood. If still no good, you will have to check the circuit from the ignition switch to the injectors.
If you got a steady light from one terminal, the drive circuit is good. Now check the ground circuit: Put the lead of the testlight on the positive battery post, and put the probe of the testlight into the injector terminal that did not light up.Someone will have to crank the car over for you. If the testlight is blinking when the car is being cranked, the injector circuit is working right. The blinking light means the computer is properly grounding the injector circuit to fire the injectors. The ground circuit leads direcdtly from the injectors to the computer. When the computer internally grounds that injector, the injector will pulse, or fire. Good luck, and I hope you find the problem.

86 buick century 2.5l. car sat about 6 months, no start, but when fuel is added to throttle body fires up. when i pulled the fuel line from TBI it sprayed across engine compartment. but when connected...


pressure underhood is good. i'd check the plug conection at the throttle body(injector).see that the injector trigger wires haven't been cut or crimped around the air filter.the injector can be removed from the body for cleaning,but you may want a shop to do that with an ultrasonic cleaner.does it spray at all when cranked?check all sensor connections too.

Getting fire and gas but wont start


Does it spin over very fast without much resistance? If so the timing belt is broken. Also, just because you have fuel pressure doesn't mean the injectors are firing. Use a stethoscope to listen to injectors to hear if they are clicking. Are there any codes stored? Some electronic failures will cause the injectors not to fire.

Good spark -- fuel supply line has fuel -- will not start -- either sprayed into air intake -- car immediately fires -- why are cylinders not getting fuel?


possibly a bad pressure regulator or injector module not letting the injectors fire. check out both more than likely the injectors are not firing.

I just got an 89 ford bronco. It has been sitting and i want to clean injectors cuz it won't start.Have added additive to fuel. Not helping. How do I go about doing this. Thanks.


first off check your inline fuel filter. If its clogged or restricted you wont get fuel to the injectors with enough pressure. pressure will atomize the fuel out of the injector. email if you want detailed info just email me and ill respond.
