Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.

In order for the engine start and stay running you need good spark at the spark plug, proper fuel pressure (32 to 45 PSI) , injector pulse and good compression. If you are sure you have proper fuel pressure and good spark, can you check and see if you have injector pulse as well as good compression?

Customer: replied 15 days ago.
checked injector pulse it is good engine has 90,000 miles i will check compression fuel pressure is 40psi
Expert:  Ron replied 15 days ago.

Okay if your sure you have good spark, injector pulse and 40 PSI of fuel pressure then checking the compression would be the next step for sure. Let me know what you find and we can work from there.

Customer: replied 15 days ago.
compression less than 50 psi on 3 cylinders
Expert:  Ron replied 15 days ago.

Okay then with this low compression and the amount of miles you have on it It looks like the timing chain has jumped on you.
