At injector's, need to check if you have ground pulsation, to check, connect test light on pos (+) battery terminal, now your set to check ground, at injector harness, probe wire's, while some one cranks engine, look for pulsation, if you don't have pulsation, it will need a computer, injector pulsation is control by the computer, if no pulsation, then no fuel can get into cylinder.

2000 galant turns over but wont start


As with any no start problem, you need to figure out if you are lacking fuel to the injectors, compression, or spark to the plugs to know what to start checking.

First started but had to hold the throttle down to keep it on then wont start


If it cranks but won't start, you will need to find out if it has no spark to the plugs or no fuel to the injectors.
In this case it could be a fuel pump or pump relay.

Mitsubishi Diamante 2001, Car Will Not Start, Attempts to Crank, But no Fire. Blowing Engine Control Fuses repeatedly.


For the sake of completeness, here's the full no-start Troubleshooting Guide for the 2001 6 cylinder 3.5L MFI Mitsu Diamante, but the problem with your car is line item #6 - the ECC (Engine Control Computer) is shorted/dead. Without an ECC, the Diamante will (a) get no spark, since the ignition timing comes from the computer, and (b) get no fuel, since the fuel injectors are operated by the computer as well. The engine will turn over, since running the starter motor is a non-computer controlled matter of a correctly functioning ignition switch, a charged battery, and good wiring to a functional starter motor/solenoid, but will never start.
The clue pointing directly to the ECC failure is the blowing ECC fuses. These fuses are blowing to tell you that the ECC is shorted dead.
Since the ECC is expensive, exhaustively check out all other possible sources of the problems, but with so few problems causing loww of both spark and fuel, combined with the blown ECC fuses pointing directly to the ECC, it seems that the ECC is the only culprit.
Here's a used 2001 Mitsu Diamante ECC at Ebay for $175.

4 Inspect Fuel Injector Pressure Regulator - Faulty Fuel Injector Pressure Regulator.
5 Inspect Fuel Pump - Low Fuel Pressure.
6 Inspect Engine Control Computer - Incorrect Operating Information Being Delivered and Sent From The EEC.
7 Inspect Fuel Pump Strainer - Clogged or Dirty Fuel Pump Strainer.
8 Inspect Ignition Switch - Improperly Connected or Faulty Ignition Switch.
9 Inspect Battery - Battery Discharged or Faulty.
10 Inspect Battery Cable - Coroded, Broken, Shorted or Poorly Connected Battery Cable.
11 Inspect Solenoid - Starter Solenoid Faulty.

The fuel pump strainer is a sock-like strainer in the fuel tank on the input side of the fuel pump designed to protect the fuel pump by straining out any debris in the tank (similar to the way that the fuel filter protects the engine/fuel injectors/fuel pressure regulator).

2002 mitsubishi diamante won't start, it sounds like it's trying really hard, after about 7 or 8 times it will barely start, try to drive and it stalls out.


Check your fuel system: From might be dirty: Spark plug, Fuel filter, fuel pump, fuel injector, EGR and your high voltage and also your distributor check it also. Some the computer box faulty..

1994 diamante wont start. battery is good, car started earlier today. tried to start car, lights all work, fuel pump turns on, car wont start. any suggestions


check to see if there is any spark from the spark plug. Take out a plug and hold it (in pliers) close to a metal part of the motor and get someone to turn it over. you should see a small spark. If not then check dizzy cap and rotor

1994 mitsubishi diamante wont crank sounds like the fuel pump is working


You should not be able to hear the fuel pump running as the fuel system should be continually pressurised. If you can hear the pump running (i assume with just the ignition on) i would suggest the pump is faulty and not delivering the required fuel pressure to open the injectors.
