what would be the most common problem if getting fire to plugs and fuel to ingectors but want crank?
Did a engine swap 89 ford f-150 from a 5.0 l to 5.8 l also changed the ecm that was with
the 5.8 l have good fuel psi plugs fire good but want start unless starter fluid is spraid
throttle body if objectors weren't fording what could I have missed?
How does it run after it starts?
It stops as soon as the starting fluid burns off as long as I keep adding spray to throttle body it keeps running. Again it has good fuel psi this didn't start till the engine swap.
It would have to be injector firing issue,turn it over a little bit,then pull a plug,see if it is wet or dry.
More than likely if not cranking it will be dry,check the fuse,s,make sure there were none blowed during engine replacement,then check for fire at the injector,
Was getting a bit of input on just what might be going on before starting back on it. I haven't even checked the injector for fire was really trying to save a lot of time tracking this down. One thing I failed to mention was the o2 sensor isn't hooked up. I'll be sure to check both the regulator and objectors first thing. Would you think the 02 sensor not pouted up would have any effect on this? And ti's for your input on this. If you have any other ideas plz send them my way.
Your input is very much appreciated. I'll let you know what I find. TKS
the fuel pump run
if not check the fuel gas pressure regulator
I mean is runnin
For what is it worth. On old aircraft air cooled engines the easiest way to check a non start issue was to spray a little propane (starter fluid) into the intake. If he started or fired and wanted to run it was a sure indication of a lean fuel mixture problem. No electronic then. Also, not having O2 sensors would result in a rich fuel mixture once you get the engine running. Could cause damage as the engine will run hotter.
