My Colt cranks, but would not start, after it was parked over night. The fuel injector would not pulse and would not pump any fuel. There are no error codes from the computer (Mitsubishi). The fuel pump has pressure and electronics are fine. Thanks in advance!
Do you
have the same problem?

See if a fuse or fusible link is burnt. This car was very good with air flow sensors. The timing belt was the biggest reason for no spark. If it seems to crank a little fast see if the belt broke.

There are sparks, so electronics and fuses are fine, it is just no pumping gas, and there are no error codes from the computer. Thanks for the reply though.

Cranks-fuel, available behind injectors valves, cranks- electrically ok- spark?- Good spark during cranking. Compression?
Fuel pump not running. You have pressure so try squirting some gas in(tiny bit). The engine controller is the injector driver, both in crank, and run key positions. Maybe the wiring going to the interior engine controller is bad somewhere, or the controller is bad. The fuel pump relay has two windings, one generates a field coil and acts as a magnet, and the other gets pulled in by the magnet and if it has ground it sends the voltage through the fuel pump. Whats the compression? It uses a airflow sensor for running. It uses other sensors but the airflow sensor is the controllers chief of command. If this sensor for any reason does not report to the controller, no nothing. Also, if you have no injector pulse, the controller is either not being told to act, or it hasn't ground or power from even a small fuse in different locations under the hood(1) or in the interior(fuse box). The most problems they had were timing belts(affects airflow sensor and compression, or fuses and circuitry(wiring problems including connections. Its an old engine, probably a 1.5. Those cars were great, and I owned two myself. 77's but I did play with quite a few, from 83 to 99, successfully. Do you hear the pump running ok? It may be a supply for injector driver, distributor(on some) or airflowsensor problem. I really hope you can get it. It bugs me when I know any car has problems. Your so welcome, I love answering, but I'm not an expert, just never, ever give up, unless of course, it is fixed, and I said 'down the road". Lol I'll always give you as much help as I can. Good day.

The car runs again after the computer is replaced. Now, does the computer needs to recalibrate? Thanks for helping! Cheers!

No, when it started up, it may have a disconnect code, it will go away in 225 starts. In 93 it was self learning and not yet sophisticated to change any calibrations according to different driving habits. A transmission computer was more sensitive for driving habits and shift points. If the check engine light comes on, it should turn itself off in a short time. You should be ok. Cheers to you also. And thanks.
