HELP! Is it piston rings, fuel pump, i have no clue!

[gwmcgowa]

My 1989 5.0 recently started turning over for about 5 seconds before it actually starts. it has new plugs, rotor and cap. I thought it was a fuel issue so i replaced the injectors, runs better but still wont start right away. My fuel pressure gauge sits at between 30 and 40 psi at all times. It has an aftermarket fuel pump which turns on and off manually. My frined seems to think i have some rings going out and that this is the cause.. Any input?

Unless your fuel injectors or rings all decided to die at the same time, I don't see how either of those things fit the description of your symptoms.

Pull codes
Check for spark
Find the technical thread index a the top of this forum and look for JRichker's No Start Checklist.

Something cheap you can do is, replace the fuel filter, it probably needs it anyway. Id check fuel pressure then next, and run a compression check, all very easy to do, and you should have your answer

Check your timing, if your timing is off a tad it will do this.
