  1. Sorry, I am driving a 1987 Nissan 300zx Z31. I figured since it was in the Z31-300zx part of the forum I didn't need to specify. Thanks G-E for the advice! I will try and fix what you said might be the problem!
  2. I have been experiencing a problem with my fuel pump running. I put in a Nistune type 1 board into the ecu to tune my car, got it to run, but the fuel pump would cut out after running for about 30 seconds. It would prime the rail, but there would be no more fuel after running for 30 seconds. I replaced the fuel pump with a walbro 255lph, hoping it would fix the problem.

I could actually take my foot off! Then, the thermostat would open and coolant started leaking from the radiator cap. After that happened the engine started to dip in rpm and go back up a couple times then it died. So I replaced the overflow/ radiator cap lock part and it didn't want to start after. It would backfire out the exhaust, but wouldn't start. Again, everything is timed because it idled fine before replacing that small
