2002 Chevrolet S-10 Repair Question
S10 4.3 pickup won't start at tdc #1
Reset the valve timing-put engine no.1 piston on its compression/TDC and align crankshaft pulley markings to TDC/0 and restab the distributor making sure the rotor is pointing to no.1 cap tower
It doesn't have one of those plates on the timing chain cover. Computer adjusts the timing. I brought #1 piston up to compression stroke. I put rotor on #1 now it doesn't, start it just pops.
Still need an answer to my question. The computer adjusts the timing so I can't reset .
Its probably 180degs off-on the exhaust stroke-I'm aware about the computer controlling the ignition timing.Some need the EST wire disconnected to adjust the ignition timing
Cranks and not start: http://www.2carpros.com/articles/car-cranks-but-wont-start
Car starts now but it shakes and smells of gas.Added gum out fuel injection cleaner in. Fuel pump is ok. Fuses ok. New distributor, plugs and wires. Prior to all this the car ran fine, pulled into garage, turned car off for a few hours and then when turned on it shook violently and banging noise. Now while it starts it smells of gas. Idles for 10 seconds and then quits.
Check the fuel pressure if its within specs with a guage
It does set the timing through the computer but you still have to manually set it right and then have the timing advanced with a diagnostic computer. The clunking is prolly one of the timing guides broken. And the timing mark for the crank is on the block not the cover
