Heys guys...I took my upper cover and v/c off yesterday to align my cams correctly (one tooth off)....and when i put the distributor back in it cranked w/o a problem but you could tell it was off time...upon trying to adjust it, i could not find the right spot....I thought maybe i flooded it so i changed the plugs and let the gas evaporate...put it to TDC and put the dist. rotor on the no. 1 cylinder, still no fire...I took the #1 plug out and it was soaked with gas....So as of right now, it has no spark plugs and i am letting the gas evaporate futher, as well as letting the plugs dry...Please help, i am installing some laughing gas:D sunday and i need my car to be running...lol It is a 93 240 with a KA...thanks guys

Ok....i went out after 30 minutes and put it at TDC and reinstalled the spark plugs....aligned the rotor at #1 and it fired long enough for me to hear the exhaust (400 rpm) and then died.....what should i do next? It fired but it died after a second or so....

Is the rotor coming out where it should be when on no.1 TDC? That intermediate gear/shaft can be a booger if you didn't mark everything good when you took it apart.

I started by setting the shaft into the oil pump about where I thought it should be, setting it up in there and seeing where the dist came out. Luckily I did mark the position of the rotor exactly. It took a few tries and I had some help, but it turned out to be not such a big deal after all. I had more trouble priming the oil pump.

I checked all the wires for spark cuz i was thinking maybe one cylinder fired and the others didn't so it may have killed the rpm...i wasn't very impressed with the spark of my wires, maybe a year old (Accel 8mm)...i am gonna take the dist. cap, rotor and wires from a friend of mines wrecked 240 tomorrow and see if that works...i have tried it one tooth ahead of the No.1 cylinder, on the No.1 cylinder and one tooth after the No.1 cylinder at TDC none of them will fire the engine...

Make certain its at TDC on the COMPRESSION stroke for #1, usually its much easier to line everything up with the valve cover off, that distributor is a ***** to get right.

I am making sure it is the compression stroke.....i have done it about 7 or 8 different times on TDC and firing on No. 1 . Well i am going to bed...i have driver improvement school in 5.5 hours

Set her on TDC(compression stroke) and align the cams. I had a problem with timing when I dropped my engine 3weeks ago. It was the exhaust cam one tooth off. After that she started one shot.
