You should have close to 12 volts and then it drops to 0. That is the ecu priming the fuel system. Once you start yu should have 12v constant to the same wire. If your fuel pump is functioning ok, scan ur ecu for trouble codes. If there are no codes look into your coil and your icm in the distributor. Very commo for failure. Once the car dies, remove any spark plug wire on the plug side and put a plug into the end of it. Put the electrode of the plug close to a bolt on the valve cover and get someone to start the car, see if the plug is sparking. If it is you have a problem with fuel delivery, may not have injection pulse. You may also have a main relay failure

SOURCE: oil around spark plugs on 1992 honda accord

Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.

SOURCE: 1996 Honda Accord Rough Idle Even After tune up

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

Fuel pump fuse is good. didn't drop the tank. did tune up day before . cap, rotor, plugs . drove 15 -20 miles then died. still sound like ignition switch?


ok slow down, it stalls, that is all we need, no need guess.
and tune up don, but you skipped the fuel filter? and air filter,?

STALLS 101.
1: lost 12vdc to EFI system. lost elect. power. easy to test , easy to see. you can attach a DMM set to 12v at the IGN output wire.
and see if it drops to zero as engine dies. sure can.

2: you could , check for spark at death, got spark
and work that path if spark fails.
3: lost fueling, (sparks soaked in fuel x 4? ) then its flooding
if dry spark tips x4 then lost fueling , so try test fuel.

you failed to say, is this a hard fail , i t dont run now.
or is always random... just a lil hint.
assuming power is hot at all EFI fuses.
then fails only 3 ways,
1: lost compression hot (if solid lifters, lash never set)
2: lost spark'
3: lost fuel or flooding.

if flooding use WOT, in this super secret mode works, Wide open throttle cranking, clears floods. (ecu cuts all fuel in this mode)
