on my 89 iroc i finally got the thing to act half way right. i put a new pressure regulator and a fuel pump relay in it.at first when i turned the switc h on the pressure went up to about 5psi and drop rapidly,now it goes to about 10 and stays put,but it suppose to be between 32&47 somewhat in that range.it is hard to start and with the help of starting fluid it will crank but runs like it is missin and weak.please help me get my baby running.
