Possible fuel Pressure Problem
#13
Yes I did a fuel pressure test and it did not have any pressure what so ever. I tested the fuel pump before I removed it. I used a power supply to apply 12 volts to the pump, but it did nothing. So I then removed it and tested it while it was out, same result. While I hade it out I tested the connection with a volt meter to ensure I was getting the 12 volts all the way to the pump, and it showed that power was present. Now all I have to do is get a new fuel pump I guess and hope that is the issue. I have read about some people using different style pumps. Is it any difference from using a OE style pump as verse a aftermarket pump like Walbro or such? Again thanks for all the help.

Sounds like it is the pump, I can't think of anything else, if the power is obviously there with no pressure,the pump evidently can't seem to pump the fuel needed. In other words,its shooting blanks.

The original problem the car had, was that it would lose fuel pressure while driving and shut off. Then 10 minutes or so the car would start back up. I am trying to help out a friend to get this thing running right again. Could the original issue be due to the opti-spark starting to go out? either way once I get the new fuel pump in I will see what the car is doing or not doing. I am not very familiar with Camaro's so I am thankful for any and all help. Thanks

i would say the old pump was overheating and shutting down. dont use the cheap pumps. for some reason i was thinking i have a walbro but its a granatelli 255. they may be made by the same company. seems to be working ok. i opened the plastic bucket and fit the pump in and used a plastic welder to put back together. did you use the hatch method to get the pump out

Probably due to fuel pressure bleeding off in the system. I would think that it is normal.
