No crank,no start 95 5.7tbi

My truck was running perfect this morning,shut it off then tried to move it about an hour later and it clicked twice then nothing. The hazards are lit up along with all the other dash lights with the interior light switch off. Thought it might have been the solenoid so I just swapped the entire starter with a good one and it still does the same thing. I’ve never seen it do this before lol what could be the issue?

only since the hazards are flashing im thinking possibly a security issue?

It’s never had a security system

Main positive from the battery to the starter could be corroded and bad or a bad ignition switch. I would turn the key to on and manually jump the starter. If it starts then the switch is the problem, if it won’t crank then the battery cable or one of the grounds is bad. Just replaced the starter on my 90 and the positive cable was in such bad shape it partially crumbled when I disconnected it so it got replaced.


Also just thought of one other thing, if the starter is engaging but not turning try to rotate the engine by hand with the ignition off to make sure it didn’t seize up for some reason.

See if it will start while moving the shifter around park and neutral.

For testing only, bypass the clutch pedal switch with heavy paperclip.

I’ve been pressing the neutral safety switch with my hand to be sure that wasn’t the problem,temporarily bypassed it as well and still does the same thing

Could still be the ignition switch, or if the key is not turning far enough the tumbler. Will it crank when jumping the starter with a screwdriver, or since it’s a manual have you tried bump starting it?
