5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
Did your compression change? If it went up and the starter was already weakening, it might be showing now that it has to crank against more compression. Nut yeah, check the basic stuff like fuel pressure, timing etc.
sorry guys, the answer is that it is cranking for like 5-8 seconds before it starts. It doesnt do it every time, sometimes it fires right up and I had .020 shaved off my heads so the compression did go up a bit.
I checked my fp and its perfect 38 w/vac 41 w/o. Its weird that half the time it fires right up and the other half it takes a while to start. i'll keep f***ing with it and see what happens
