2000 caravan won't start after timing belt change Sign In

2000 dodge caravan 3.0 150,000 miles.

I replaced a friends timing belt and water pump on his van. during trying.to
find top dead center another friend helping me dropped a 1/4 inch extension
for a 1/4 inch drive got dropped down the #1 cylinder. so I proceeded to take
off the heads (replaced all gaskets) to get the extension. no damage to cylinder or piston. got all timing marks lined up and put.back together. but during... the distributor got pulled off. now van wont start but sounds like it wants.to. noticed it wasnt getting spark so changed the ignition coil. no start..... sure.could use any sugestions????

I don't know why that extension couldn't have been retrieved using a magnet instead of removing the head.

Check to see if you have injector pulse. If that is missing also I would suspect a problem with the Crank Sensor.

Make sure the main relay is supplying power to these components also.

I tried to get it out with a magnet and a scope with a monitor but was unsuccessful. how do I check for injector pulse? the crank sensor is coming off the distributor housing... correct?

You check injector pulse by plugging a noid light bulb into one of the injector plugs and crank the engine.





The Crank sensor is attached where the bellhousing meets the engine.

Was it running before you did the timing belt job?

my friend said that when his wife went through a water puddle it died right in the middle of it and then wouldn't move after that. I believe that's when the timing belt broke and the water pump as well...

Re: 2000 caravan won't start after timing belt change Sign In

did you check for codes?



then its the BASICS -
Is there 12v at the injectors ?
Is there 12v at the coil?
Is there spark at the plugs?
is there fuel pressure - the PSI is?

This body style exactly - saw it once only with a huge puddle and instantly died. Look if any chance but the one I saw drew up water into intake (which is low in splash range) and croaked the engine! Hydro locked and snapped it beyond repair. Still cranked. Water evidence was there and think you would have noticed something like that all wrong and hope I'm wrong,

My thinking - heads were off - timing drive work- had to be rotated and timed, valve's observed - wouldn't something that catastrophic have been noticed?

You all know I am an optimist ... knee deep in Sh!t - I know there is a pony somewhere.

You would think you would have to notice that if only oil so full and that classic no compression sound. Has to be totally rare but was a puddle hit by surprise not a flood thing.


Wasn't involved except saw the set up and new whole engine go in at a friend's shop who got that job. Also not sure who paid for it as the intake was clearly too low by opinion and IDK if ever changed for others or what. That one was a surprise not someone driving thru water too deep that you see too often out there,

I had a Dodge Ram with a Hemi do this. It wasn't real hard to tell on this one though. The connecting rod hanging out the side of the block was a pretty good indication.

Obvious is just that and seen that. What caught my attention was the exact same vehicle and placement of air intake on this one. Still just an "out there" guess for a reason. I think pistons collapsed. That case other vehicles had no damage only because of the air intake placement! Unlikely still in that case for any of it,

Trying to think how driving thru water would blow a timing belt. It could possibly derail a belt if water got between the sprockets and belt and lifted the belt off. Hydrolocking usually doesn't take a belt out, unless the crank stopped instantly at high enough engine speeds. Maybe the belt was on its way out?

Maybe you should do a compression test, just to see what you have.

Doing heads on those are not fun. Especially if you don't have the special clip retainers for the lifters.

Re: 2000 caravan won't start after timing belt change Sign In

Perhaps the puddle was just a coincidence, and this thing had an original timing belt in it. Had the same van with the same engine before I bought my girl the Camry. About a year before I got the van I did the timing belt for the owner as it snapped on him without warning.

Good thing this isn't an interference motor. I'd second the c-test. With unknown history on this engine its worth finding out what you have.
