I am sorry for the long waitwill the van somewhat run on starting fluid or carb cleaner if either is sprayed down the throttle body butterfly ?
Customer: replied 1 year ago.
Yes started with carb cleaner and will stays running. Starts right up again. What do you think may have been causing the no start.
Expert:  Gary replied 1 year ago.
if the engine will run on carb cleaner then we know this is a fuel issuethe odds are the fuel pump is badwith a gauge connected to the test port drivers side rear of engine next to the distributor on the fuel line is the test portthe fuel pressure should be 60 to 66 PSI key ON engine OFF the odds are it will be under that PSIif it is the fuel pump is bad and will need to be replaced to correct this issue
