I've got a 88 samurai in the shop giving me an issue. It had a 95 16v in it and we sent a 97 16v out for a rebuild. Port and polish the heads, 20 over pistons, 10 shaved off the deck. The cam has been reground by altered ego motorsports and the 4 degree timing key was installed. Timing has been set at about 11 degrees. I'm reusing the original 95 california harness and ecu. Cold starts take some cranking, pedal pressure makes no difference. After warming up it'll start right back up easy. There's a new egr valve, egr temp sensor and new maf. "Cold air" intake. Injectors have been re sealed. Fuel tank and pump are new from petroworks. Fuel pressure will sometimes not hold at 40 key on, sometimes will drop as soon as the pump shuts off. Holding or not doesn't matter. Return line was pinched, and fuel pressure held solid so I don't suspect injector leakage. IAT, and ECT test good with good voltage. What should ISC voltage be key on, is it readable? TPS has been tested and passed. Throttle body and IAC is off the 97. The 95 was disassembled for cleaning and the iac rubber gasket deformed so unusable. Any suggestions?
