Hi my name is Chris and i have a 1990 Toyota pickup and i can't get it to start now to begin with the truck only starts if it has starting fluid sprayed down its throat but it will only stay started for like 5 seconds but even less when i put my foot on the gas now with that said i think it is a fuel problem so i have checked out the fuel pump, filter, and relay and they all check out now i am new to the whole mechanic think so any help would be greatly appreciated

 

Welcome to Yotatech.
Click on the link in my signature, and download or use the online version of the Factory Manual. Look for your year vehicle, and then look for the MFI Diagnostics section. Print it out, grab a multi meter, and start testing step by step. There are so many things this could be, you need to start testing and stop guessing. For starters, you will want to find out if there are any codes by jumping the TE1 and E1 ports in your diagnostic connector, and counting the flashing light on the dash. If you have a code, fix that problem. Then continue until you do not have any more codes.
Oh, and once in a while, throw a period in your sentences.

 

Thank you very much for the manual.
