Hello and welcome to JustAnswer!

Do you still need help?

Customer: replied 1 year ago.
Car shutoff while driving. Thought it was the alternator. Changed alternator battery and ignition coils. Checked the fuel pump also. Is there any other reason the vehicle will shut off? It's cranking but not turning over
Expert:  sprinkles08 replied 1 year ago.

'Cranking' and 'turning over' are synonymous. The starter does engage and turn the engine, correct?

Customer: replied 1 year ago.
the starter does engage
Customer: replied 1 year ago.
Ot turns the engine
Customer: replied 1 year ago.
It turns the engine
Expert:  sprinkles08 replied 1 year ago.

You physically checked for spark and found none on any cylinder?

Customer: replied 1 year ago.
I used a spark plug tester. My next guess is timing belt
Expert:  sprinkles08 replied 1 year ago.

Have you checked injector pulse?

Do you know what fault codes are setting?

Customer: replied 1 year ago.
No I haven't check that and don't know the codes setting
Expert:  sprinkles08 replied 1 year ago.

The first step in diagnosing the problem will be to use a scan tool or code reader to see what fault codes had set.

Customer: replied 1 year ago.
Ok will do
Expert:  sprinkles08 replied 1 year ago.

Let me know what you find.

Customer: replied 1 year ago.
Will do
