When i turn the key to on position sometimes the fuel pump doesn't prime, thought it was a fuel pump issue before so i replaced it with new a one now the car starts up good, but sometimes the fuel doesn't prime and the car doesnt start sometimes....could this be a faulty ignition switch or a problem does has to do with the ignition system? help me out guys

 

Try playing around with the key in the ignition. I just had this issue today with the key not returning to its normal position after turning. Resulting in the engine turning off from not receiving the ON signal. Haven't fixed it either. Here's hoping someone else will chime in to which specific part/s need replacin

 

RDAYAO, if the pump is not priming, you may want to re-solder your main relay. This is the most common culprit for your type of problem. Rule it our before you do anything else. Cheers.

 

I've replaced the main relay with a new one already, my old one had burnt points...tried resoldering it but i just got a new one
