Water pump change and now wont start

Yes,there is a special wrench that fits the water pump. You have to loosen bolts on pump and put wrench on pump and turn pump to get belt on. Then tighten pump till marks line up on tensioner,then tighten the pump back down. Be sure to roll the engine around twice and recheck timing marks on crank and cams.

It's possible that the defective plugs blew out the Ignition Control Module. Are you getting any spark from the plugs? Try removing one of the plug leads, hold it about 1/4" from a metal surface, and have someone crank the engine. You should see a strong spark. If not, then I'd replace the ICM and see what happens.

sounds like a bad crank sensor on the engine

clogged catalytic convertor

Did you check the water pump? If the impeller is broken it will not circulate any coolant.

I would check the air filter, pcv valve (take it off and shake it), spark plugs and wires to see if it's just time to change em'.

Hi,

I had a similar problem. It was my waterpump. I got lucky and was close to dealersip, so no major damage. Before it failed (about three months before) I noticed the decline in acceleration, dealership missed diagnosing the problem twice. They finally figured it out, when it failed and started clunking in the truck. Was an expensive fix but not as bad as destroying the motor.

Get the water pump checked asap. they changed an air line valve connector thing first which did not fix the problem.

Also, I had a fan belt changed just before the water pump failed. The new fan belt put too much pressure on the failing water pump, causing it to crash and burn about one week after the belt change.

Hope this helps you.

You will have to see if you have spark and gas first of all. When you first turn the key to "on", you should be able to hear the fuel pump cut in for just a couple of seconds. If it doesn't, check fuses and relays. If they are okay check to see if there is power at the fuel pump. If there is, you need to change the fuel pump.
Get a timing light and hook it to any spark plug wire, and see if you have spark. If you don't, first, i would check the timing belt. If it's okay, try changing the ignition coil pack.
Let me know how you make out when you get that far.

you could have accidentally overflowed the transmission fluid. That would cause problems

Hi my name is Allen!
Not sure how changing a water pump could cause a no start, but it sounds like the main Ignition Fuse may have blown some how, or you accidently knocked a connector loose some where. Check the PCM and make sure all the connectors are plugged in tightly.
