Resolved 92' Galant Diagnosing a hard start condition and random low revs while running

[sebas-1024]

Hello,

The car is a 92' Galant with a 4g63 DOHC. It had a hard cold start so I went ahead and ordered an NTK Coolant Temperature Sensor (as was suggested to me in a previous thread) from RockAuto thinking that was the problem, today I replaced the previous sensor with the new one hoping that the car would start right up but it didn't, I think it even took more tries to actually turn it on, when I finally got it running, it would randomly try to stall a bit and then return to normal, given those symptoms I suspect that the actual problem is not the Coolant Temperature Sensor but the fuel pump, does this seem like a rational diagnosis?

Assuming that it is in fact the fuel pump, can anyone point me to an reliable (and if possible cheap) fuel pump make & model that I can just purchase once on and not think about for a few years? I live in Venezuela and most if not all fuel pumps that you find here are cheap knock-offs and they don't last very long, for reference, the current pump was installed on December 29th so it lasted about 5 months.

Thanks in advance for any help!

Did you fix your ECU yet? This could be related.

Not yet, but it was the Fuel Pump, it was replaced and it's working now. Thanks!
