89 Spider Starter Problem
I have an 89 Spider, starter seemed be dragging so I thought I would replace it.
To make it easier I removed the plenum, took out the old starter and put in the new one.
Put everything back together, turned the key, but no cranking.
Battery reads 12.62 junction in the engine compartment reads 12.62 but no cranking.
Is there a post I can go to...need help.

I would re check that all the wires are connected correctly.

When I rebuilt my engine, the ground fell off.

Hope its an easy one for you.

Good luck,

Joe, question for you, since you recently removed the plenum: To access the rearmost bolt under the plenum, did you need to remove all of the wiring to the injectors and sensors in order to remove the wiring harnesses blocking access from the rear? Is there a non-destructive way to separate the plugs from the sockets? Seems like a nightmare!

joe1958 01-02-2017 10:26 AM

we did not remove the wiring, just the plenum an the hoses.

Trying t figure out how the starter engages, does the small wire on the side of the solenoid engage when power is given to it?

spiderserie4 01-02-2017 11:22 AM

yes, the small wire attached to the solenoid (usually a simple spade connection) makes the starter engage when IGN key is turned to 'start'.

the thick red and the thick black wires both attach to the upper stud with a nut (the longer stud)

The other connection with the stud (the shorter stud) just has the bare braided wire coming out the starter motor itself (field coil terminal)

I wonder if you wired the thing back up wrong?
Nb.: disconnect battery when doing anything on/near the starter:)

Plenum bolt
Joe, How did you get to the rear most bolt under the plenum, that holds it to the support bracket? I got the others from the front

Yes that plenum stay bar likes to get in the way!!
When I did my engine mounts, I got at both those 17mm bolts from underneath with a long 60cm extension on a ratchet....but car was jacked up.

But, many people here have somehow got at that rear bolt, also going in from the front as you have done....

great photo here showing what you are up against

plenum bolt
What worked for us was using a short box end 14mm wrench but had to reach from the front around the bracket putting your hand near the block and pull towards yourself.

starter problem
Trickle charged the battery to 13.0 volts, and now the car cranks hard.
New fire! Need help

Measure battery voltage with everything off - a good battery should show ~ 12.6V. Next measure battery voltage during cranking. It must remain above ~ 10.5V for the computers to power on. It can sound like it is cranking over fine even when system voltage drops below that threshold. If either readings are low, check all connections in the battery to starter circuit (esp grounds) and re-charge the battery. If it remains low, consider having the battery load tested to see if it is serviceable or not.

L-Jet Diagnostic
Have you tried the L-Jet diagnostic (available here )?

joe1958 01-02-2017 04:56 PM

Yeah I have that but I cant perform most of the checks because the car wont start.

dghii 01-02-2017 05:42 PM

While cranking your car, does your tach needle move or does it stay seated?

If tach doesn't move, your crank position sensor may be disconnected or bad. Given that you just did the starter, look for the two connections for the two sensors. There are two 3 wire plugs and sockets located just forward of the washer fluid tank (basically, just above the starter). The two connections are detailed in the L-jet troubleshooting guide.

Your car does not have to start to check these things.
