I have a bmw e30 325i it cranks but will not start so what can I do to fix it?

First, remove the engine drive belts. Then see if it will crank over. I have seen an alternator that was seized keep the engine from turning over. If it still will not turn, using a pipe wrench on the crank pulley see if it will turn. Pull the spark plugs. If water or too much fuel is in a cylinder it will hydro lock the engine.

Do you know how to check fuel pressure ? Check for spark at the spark plug ? You need to find out what's missing an go from there on the system that's not working . Fixing Car That Cranks But Doesn Start Up Watch a few of these type videos an see what your vehicle is missing .

Hi there I am a mechanical technician engineer I fix the things normal mechanic cant! I fix mechanical and electric problem no matter what it is the problem with it!!!I I am very good and bless in my work I am 5gen mechanical engineering technician never have a problem I can not fix Its the ignition switch also have to check out the grounds for the whole car do a voltage drop test to find out the problem

it may have an engine immobiliser fitted, just a thought as I cant see why removing a fuse would cause those problems. I would be ringing the BMW dealer that you bought the car from as they may be able to help you without charging you an arm and a leg for something simple that you can fix yourself.

the negative terminal of the battery SHOULD NOT BE connected in the ignition coil. the negative terminal of the ignition coil is connected to the condenser in your distributor.

1. make sure that your spark plug is working. try using other sparkplugs to check.
2. check if your high tension wires are working
3. if numbers 1 and 2 are ok, then just replace your iginition coil.

if the key is good there should be no reason for it not start,the alarm will not lockout.is the engine cranking?

Need more info. Do you hear the fuel pump kick on when you turn the key to the on position? Does the engine crank over at all?Do your lights go dim when you engage the starter?

maybe the crank position sensor, long starts are usually due to the fact the computer doesn't know where the NO.1 cylinder is, so he fires at random and eventually he nails it, therefore the car starts.

The crank position sensor tells the computer where the NO.1 piston is at and he knows when to send the spark, but u should have a check engine light on in this case.

I think you have the wrong clutch housing installed or the flywheel spacing from the block is wrong. When the switch was made to manual from auto there should have been something fabricated to shim the starter into the correct alignment with the new flywheel's ring gear the same as it used to align with the flexplate. Good luck with this one
