I have aE450 Econoline V10 petrol 1999
Since battery removeal and replacement engine refuses to start.
It does turns over but refuses to start.
any help would be much appreciated
Wiring diagrams also urgently needed.
You need to put a scredriver in the end of one of the plugs to see if you have spark. If you have spark, you may assume you might not have fuel. Somewhere along the fuel rail you might have a test port. It looks like a tire valve. Hold a rag near the fitting and poke the valve in the center to see if you have pressure on the fuel rail.
If you don't have fuel, and the truck has been towed or been in a fender bender, the fuel safety switch may have tripped. Look in the owners manual for the location. I assume they are still using these safety switches on the later vehicles.
