if you have 12volts to fuel pump and you have no fuel pump turning on , you must check the ground connections for fuel pump/frame ground point....it is possible when replacing pump that they fell off/broke off...

if you can get engine to start with dumping gas into the intake manifold it has to be fuel problem...


if the starter continues to run without key in crank position , the starter appears to be damaged. the starter solenoid contacts must be welded together,,,don't crank for more than 10 sec. then wait 3 minutes to crank again...

No relay.
Solenoid is on starter.
Purple wire is start wire.
You might be able to jump starter at start fuse.
