hey i have a 93 Si that i just put a 98 gsr into. the harness is a 95 gsr but i spliced the injectors and distribitor wires so i can use the obd2 parts. my problem is that i finally got the fuel pump working and fuel is getting to the rail. the plugs are sparking, but they are dry. so no fuel in the cylinders?? and help please. thanks Ace

 

I take it all of your cam and crank timing are right?
You sure you spliced the injectors correctly? Why would you splice them in? The Si and the GS-R both have 235-240 CC injectors. If you know that the Si injectors worked, put those in and see what happens.

I know that the '94 + GSR injectors are the same style of injector, just different plug. I doubt anyone could screw up the injectors, but you would have to screw up all four. It would run on at least 2 injectors. I'm wondering if what you did to the distributor is working. Have you checked for spark? You didn't mention that so I thought I'd throw that out there. Did you solder the wires?

 

i hope i soldered the right wires cause they were all the same colors on the 95 and 98 harnesses. i had to change the plugs cause the 98 injectors wouldnt plug into the 95 harness. same with distributor. yes theres spark. so the dist is working but i guess no fuel. i think i might take an injector out and turn it over and see if it shoots fuel. any other ideas? hey the ecu is still the p28 from the SI. im going to get it chipped just wanted to get the car running first before i send it off. it should still start correct??

 

Are you runnign on an OBD2 ECU? if not i question why you would change anything. I have a 97 GSR in a 92 hatch running on a 95 GSR ECU and it just pluged right in. Aside from some wierdness with the IAB solenoid everything worked perfectly from the get go.

E-mail me directly if you need help.

no i have an OBD1 ecu. the p28. the connectors on the 98 dist and injectors were different then the 95 harness i had. i schecked the injectors and they are clicking if i put powere straight to them. i tried to switch the wires to see if that would make a difference but it didnt. me having a non chipped p28 wouldnt make a difference would it? thanks
