Spark plugs What kind advise do you have on changing the rear spark plugs in a 1998 Chevrolet Venture

Take the 2 engine mount bars off at the rad support then pull the motor forward (rocking the motor forward) to gain access to the rear plugs.BUY A SPARK PLUG WIRE SET and change that too,one at a time.The spark plug wires are usually stuck on the plugs and can be damaged removing them,PLUS you do not ever want to go back there again!.Use a come along to rock the engine forward.

no its not easy but i always do them from the top it helps to have different length extensions and swivels

It would help us help you if you give us the vehicle's year, make and model and engine size.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

This will help.
Thanks.

This is usually caused by carbon traces in the spark plug connector. You must pull the boot off of the spark plug and look down the boot for the carbon trace.
Do not pull the boot off of the plug by the wire as this will seperate the wire from the boot.
It is very apparent on the spark plug porcilin.

You can remove the engine struts(dog bones) mounted over the top of the radiator. Use a ratchet strap, attach one end to the engine hook on the driver's side dog bone mount and the other to the radiator support. Pull the engine forward, you can then access the rear spark plugs. You have to make sure your spark plug wires and ignition coils are not corroded also.

Could be fuel pump , fuel filter, alternator, have you had a tuneup lately changed spark plugs recently. try doing some of these things first. If you turn the key on and all the lights work probably not the alternator

what a pain. basiclly you must remove them from under the car and from the back. it is a pain so you must relax and breath it will test you. Long needle nose pliers will help remove the wire and I would have a new set of wires on hand because they come apart and you only want to be in there once.

Check/ replace your sparkplug and coil high tension leads.
