Problem after changing water pump
Hi,
I just changed my water pump a couple of weeks ago on my 91 vert. Everything is back together and no leaks...thankfully. But, I seem to have another problem. My 7 seems to be flooding and I can't figure out why. Is it possible that the ECU thinks the car is cold all the time and is choking it. I really don't understand the whole warm up part anyway. That's the only thing I can think of. Any help would be greatly appreciated. Thanks in advance, Rob |
Did you reconnect the water temperature sensor on the back of the water pump? Alternately, could the one in the pump you swapped in be bad?

Yeah, I get temp readings from the factory temp guage.

How many miles on the engine & body? Fuel injectors may be bleeding off fuel pressure with the car off and flooding the engine. Very typical on higher mileage cars. I need to send several sets of injectors off myself for rebuild & blueprinting.

were do you send them in to be rebuilt/blueprinted? and how much does this cost?
sorry to thread jack |
There are probably local places close to you, but you can send them off to:

That right there is why you need to send these things off to have them professionaly cleaned. That flow differance could easily create a lean condition and be damaging to the engine (especially turbo engines). Mine NA blew the rear rotor with the poor flowing injectors... |
the only thing is, this just started without warning. I know that something mechanical usually goes over time. I had no problems starting the car last week.

wait. Is there a tem sensor on the 87 N/A model? and if so, would it cause the car not to turn over if it was unplugged? I just changed my water pump, and now my car will not even turn over. i think it is the starter, but it started fine before i changed the water pump, then afterwards the car woudlnt crank... coincidence?

I don't know. I plugged the sensor back in. I don't see anything I missed. Does it matter that I had to take off the smog pump? I put that back on okay. I just don't know what I'm missing here.
And btw how I didn't know injectors could be rebuilt??? Rob |
