92 civic replaced parts still no start
I have a 92 honda civic dx,I have replaced the fuel pump,relay,and distributer cap in that order,every time I replaced a part it ran for about a week,last time didn't seem to have spark thus the distributer,worked for a week again and now just cranks once again.no hint that it may need gas ,tank is full never slightly catches like I need to give it gas ,just cranks.I don't want to just keep replacing parts for it just to not start in a week,and the question is coming before I replace the ecu,not looking forward to that expense.any advice will be appreciated,please don't post if its guess work I've had enough of that thanks

cadee884, I think you must have missed (or just skimmed over) the opening statement by LLmooleyj. The statement was, "i have replaced the fuel pump, relay, and distributer cap in that order", with my corrective spaces added after the two commas. So, we must conclude that the fuel pump is new, or at least replaced. My first inclination would be to check the valve timing in this situaton, but a faster method to verify that would be to spray a SMALL amount (perhaps a one second burst) of starting fluid into the intake hose, while it is removed at the air filter end only. If the problem is fuel delivery, the engine should start momentarily, but then quit again. But be cautious about the amount used! Too much starting fluid can destroy an engine! I have seen it happen. If the engine fires at all under those conditions, there is a whole lot of stuff working properly, and the ignition system and valve timing are both probably OK, as well as heads, pistons, valve train, camshaft, valve lifters, etc. What that procedure WON'T check is the fuel delivery components, including the fuel pump, fuel pump relay, fuel filter, fuel lines, fuel injectors and all their associated wiring because the starting fluid bypasses all that. But at least the procedure will narrow down the defect possibilities. |
