no engine light on, no i havent done any pressure test, how do i do that
Expert:  Dan replied 4 months ago.

A quick easy test is to see if it runs on starting fluid next time problem happens. If not we know problem is spark related, if so we know problem is fuel related. Let me know how it goes, thanks.

it will start on starting fuel
Expert:  Dan replied 4 months ago.

Then next step is a fuel pressure test, you can barrow fuel pressure tester from parts store for free. Fuel pressure should be at last 50 psi key on engine off during problem, if low replace the filter and check again. If still low replace the fuel pump. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
