I have a 1996 B3000 with 100,000 miles that takes two or three turns to start up when the engine is cold.
I have recently replaced the fuel filter and spark plugs and wires. The battery is only 6 months old and I don't know where to go from here. Can anybody offer some guidance? Thanks

 

First check your ECT (when cold should read aprox 2kohms, when hot 200 ohms); second, fuel pressure.

Good luck
