I got a 92 eg hatch si w/ h22 swap. When I got into my car this morning my fuel pump didn't prime. I tested both dash and hood fuses #24 and 31. I've replaced the main relay and still had no luck. I've followed some procedures for jumping it. When I jumped main relay pin #1-#7 the pump turned on. When I jumped pin #5 and #7 with key in position 2. I got nothing. Also the grounds are good including the one off the thermostat. Can anyone help me out? Thanks!

 

What ECU?

When you turn the key from off to ON(II), does the CEL remain on steady or turn off after 2 seconds?

Any CEL codes?

 

Im running a virgin p28. The cel turns off after a couple seconds. I went through and unplugged and checked everything agian, and it randomly started

 

You cannot run a stock P28 specifically for a 1.6 D-series on an engine with a higher displacement and greater fuel demands. You'll probably say it's what you have right now but it's still wrong.

 

I got into my car this morning and the problem started agian. It rained 2 days ago and it rained this morning also. Could the rain be effecting it? I drove it all yesterday off and on with no problems.

 

I know what ecu I'm running and it's only temp. Ive already ordered a Hondata s300 I'm just waiting for it to come in. But regardless of what ecu it is, the fuel pump should at least prime

 

A damp ECU would.

 

i checked the ECU and the connector and it was dry. i also opened the ECU to look if it was fried. everything was Ok. what else could contribute to my problem?

 

I took it in to a shop and he said he thinks its the ecu because its not sending a signal from the computer. So I'm gonna pick up another p28 and see what happens. He said if its not that then id have to take it somewhere else cause he can't figure it out
