The ecm may need resetting as the battery was disconnected
use a scan to to reset it and then the immobilizer may operate properly
make sure that all wiring harness connections are right and properly connected

Actually, it is a bad sensor. Change your CRANK sensor and that should solve the issue. They're around $70 or so. It's located down on the bell housing of the transmission. Not terribly hard to change. It is NOT your PCM. Whoever told you that, is out for blood. LOL I hope this helps!! :) -Jason

My bmw 1.6 e36 has lost its spark i have changed both crank and cam sensor could the lambda sensor still be the fault


Hi Thomas, You seem to have attended all that is required for the spark. Check the wiring and if it's fine I would suggest you have a diagnostic scan carried on on the vehicle. That will pinpoint the problem and allow a long term fix. Regards John

remove the plug from the #1 cylinder, and install it into the #2 cylinder , and put plug from # 2 clyinder in to #1 plug hole, connect plug wires, and start up vehichle, and if computer shows misfire on # 2 cylinder , then you have a bad plug, possibly porcelin insulator could have a hair line crack in it, hope that this information has helped you.

Motor turns over but will not start, seems to be getting gas, & spark


I don't have enough info to give you a specific answer so I've listed a bunch of possible problem that could cause your engine to roll over but not start.
Check the battery and connections, a weak battery or bad connections can cause a weak spark and stop the engine from firing.
Fuel pump or fuel filter, low gas pressure can cause to lean of a air/fuel mixture for the engine to start.
Bad gas, old gas or water in the gas can stop the engine from firing.
Bad or fouled spark plugs, could be caused by bad gas.
Ignition wiring problems, can cause weak or unreliable spark.
Bad, poorly connected or misconnected spark plug wires. Even 2 wire out of order can stop the engine from firing.
Oily spark plug wires, can cause the spark to fire at the wrong cylinder or misfire.
Worn, damaged or wet ignition components.

Car engine start shaking


you may want to try haveing the fuel injectors cleaned they can also cause miss fires also try flushing the fuel rail to flush the rail just hook up fuel gauge and turn the key on and remove the gauge from the hose and let it run into a container also look at fuel and see if the quality is good should be strong smelling one cup should smell up a small garage if it doesnt try a different brand of gas

Missing engine


were the spark plug gaps set properly with feeler gauges if they were put in straight from packet they need to be set to correct gap which could cause miss firing or it is possible the leads were not put back on in correct order and probably a good idea to reset the timing if you do not have a timing light pop into mechanic its a 5min job an honest mechanic at worst would charge you $10 .00 to do timing this would make a huge difference when starting of a morning hope this helps thanks glenn

Changing spark plugs


if i am not mistaken, half of the plugs are on the bottom of motor, follow the plug wires, they'll take you right down to them...
if you have a sideways motor, i think they're all on the passenger side, about midway down.
