Car Forum / Hyundai Cars / April 20082000 Accent GL no spark, so no start
My neighbor asked me to help him out My best guess was to replace the crank sensor, but no luck Anyone have any suggestions going forward? Helped him replace the automatic transmission with a rebuild a while back That was a real PITA Does the check engine lamp come on when the key is turned to the "on position? If not, you probably need an ECM. Be sure to check fuses an grounds prior to replacing. Did the o-ring come out with the old sensor? If not, the new sensor (wit new o-ring) is probably too far away from the crank wheel to read it. Have you checked the timing belt to be sure it's intact - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm > Does the check engine lamp come on when the key is turned to the "on" > position?

What amazed me is there was no spark (I know a spark when I see or 'feel it") until we banged on the tank hard enough to revive the pump. I assume there must be a "no fuel pressure means no spark to the cylinders" circuit. Thanks again..Hewy I don't think so. There's nothing on the car anywhere that measures fue pressure - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm > I don't think so.

I assume there must be a "no fuel pressure means no spark to the cylinders" circuit. Are you sure your banging didn't fix something else? It's possible your "no spark" and "no fuel pump" had a different common cause. If the ECM doesn't detect inputs from the Crankshaft position sensor, it won't make spark, and it will open the fuel pump relay. > Thanks for the reply HT, but turns out the fuel pump had gone south. > What amazed me is there was no spark (I know a spark when I see or [quoted text clipped - 6 lines] > detect inputs from the Crankshaft position sensor, it won't make spark, and > it will open the fuel pump relay. Good point, but after reading all threads concerning "no start" conditions, I replaced that sensor (about 50 bucks) with no effect. The "hammer treatment" was tried next, followed by an new fuel pump. Hewy |
