My 1976 280 won't start after I ran the batter dead, even when I jump it. I couldn't hear the fuel pump running (a normal sound on turning the key to the on or start position), so I replaced it. No go. Oh well, the old one was years old and now I'll have a back-up fuel pump.

I hot wired fuel pump and tried starting. Wouldn't start. I switched the ignition relay (I had a spare from a parts car), nothing.

Someone below suggested a fusable link was fried. But how do you know if one is bad. I think I'm getting spark, as the car will fire up for a brief second after it's sit a while, but then nothing, as if the injectors aren't opening.

Could my transistorized ingnition module be bad. What's up.

Any suggestions would be greatly appreciated.

Alex,

Remove the fusible links and connect a test light to both ends of each link.

I think you should check your fuel pressure first. I am not sure how to do it, but someone on here could tell you.

> Alex,

remove each fusible link and look for unevenness - the bend should be smooth. An uneven curve is a hint that the link is bad.

Use either a test light as suggested or a continuity tester (multi-tester) to see if the fusible link will carry volts... no reading = bad link.
