When you first turn the key to 'on' the drive relay will briefly send power to the pumps. Then the drive relay stops powering the pumps until it 'sees' that the ignition system is firing. So, we need to confirm that you really have spark. No spark = no signal to drive relay = no fuel injection. It'll run for a few seconds on the fuel from the CSI (Cold Start Injector) because the CSI is not under the ECU's (computer's) control. The fact it runs for those few seconds would seem to indicate a functioning ignition system. But it'd help to confirm the presence of spark.Hey, thanks for the help again guys. When I turn the key to the 2 position I can hear both relays turn on, and on the smaller relay I get a reading of 12 volts. So I think both of my relays are working. Now I was wondering if the car should be pumping gas when the key is in the number 2 position because mine is pumping very little. And when it is in the number 3 three position it pumps a lot of gas.
Here's a snip from the injection wire diagram. Maybe it'll help?Can I test the main relay?
I'll bet that means something. Danged if I know what, though...When it will run for a few seconds, I get around 34 +/- psi and at that level all seems cool. ( Keep in mind, I have cleaned all lines, new filter, 1 new pump & double verified return line is clean.) I can watch gauge & then all of the sudden pressure will rise to 40-42 and it dies.
Other times I get the 3 second run syndrome only and pressure never goes below 40 psi.
