Question about 1999 Mitsubishi Eclipse
Has a 2.0 l engine dies like fuel problem because after it dies it cranks over but no fire so spray starting fluid then it starts runs again then do es the same thing over and over again i replaced the fuel pump well that didnt help one bit I DONT KNOW WHAT TO DO AND HOW TO CHECK FOR CERTAIN THINGS AND NO DOLLARS FOR THE GARAGE .HELP PLEASE
BBB Industries have diagrams for free online. Check for power to fuses and relays to the injectors and a pulse signal to the injectors would be a first step. Check YouTube for "injector voltage test" will show you how visually.

Well, it sounds like it is a problem in the fuel pump circuit. A lot of problems don't set a code, but if you know someone with a code reader or scanner, or if you get it running to drive it to Autozone or O'Reillys, Pep Boys, or most auto parts stores , you can get a free code scan service. Only takes a few seconds, good to know if your engine computer has detected anything.
So you put a new pump in. If it turns on, it should put enough fuel pressure up to the engine. Here's how to check if the pump is turning on as it should to start the car: turn the ignition key to on, not start, and listen for the fuel pump to turn on for 2 seconds. You should hear a hum or buzz from the tank for about 2 seconds. If you do hear it, and the fuel filter is not plugged up, the engine should have enough gas to start. If the filter is not plugged up, and the only way to start the engine is with starting fluid, then the problem may be in the fuel injector circuit.
Now if you do not hear the fuel pump turn on (2 seconds) with key in on, then the problem is in the fuel pump circuit. This can be difficult to diagnose, not feasible without a voltmeter and a wiring diagram of the car, so you would probably need experienced help. If you put the pump in yourself, you are a good gear head. buy a digital voltmeter and a repair manual and go to learning while you fix it your self.

Ronald, the most important verification of the fuel pump (and the fuel filter as well), WHEN you have a no start or hard starting situation and you want to know if the right amount of gas is getting to the engine, the most important verification is to check the fuel pressure at the pressure test port on the engine. If pressure is correct to Mitsubishi specification, with just key on, not start, then your pressure at the injectors should be spot on, and if the computer signals the injectors, the engine should start at the first impulse. I'm pretty sure that some national parts stores will loan (or at least rent) fuel pressure gauges. At the pressures required for multiport injection -upwards of 45 psi and above- the correct pressure is critical for proper operation.

SOURCE: the check engine light comes on and then the engine dies
If you check under the hood and see if the fuel pump relay is clicking on and off. This may be your problem.

SOURCE: engine turns over but wont crank. checked fuel
if it runs with starting fluid you have a fuel issue how did you check the fuel pump

SOURCE: 1991 Mitsubishi Mighty Max 2D 4X4 V6 3.0L No Start.
you can get pressure specs from your local parts dept, and check injector signal with a noid light

SOURCE: No Fuel??? Not starting.
You have fuel flow but the question now is are the injectors pulsing. Given the year of the truck my gut says your ECU, Engine Control Unit, has failed. Mitsubishi had issues with the capacitors in their early 90's cars, trucks SUVs. I have been thru this with two monteros and one 3000GT, very common. To check your injectors rent a set of NOID lites from Autozone our such. Remove an injector plug and itstall a noid light. Turn the engine over, if no flash, no pulse. Remove the ECU and carefully open it up. Look for the capacitors, there should be 3, look under the capacitors on the board; if there is a grease like substance, often time it has a green hew to it, then the capacitor(s) have failed. It may be possible to replace the capacitors or simply purchase a rebuilt ECU. Be ceratin the MD number matches on the new unit.
Please let me know your results and if this had assisted you.
Thanks, Tom

SOURCE: no fuel
It could possibly be a faulty Crankshaft Position Sensor. If the computer doesn't see that the crankshaft is spinning, it won't activate the fuel pump.
