Hi all,
I have a complicated and frustrating situation that I could use some advice on. Here's the background info:
- I hydrolocked my 1998 automatic base prelude. (F***!)
After measuring the piston heights (and seeing water in a cylinder), it was clear that I bent a rod pretty good. I opted to replace the engine instead of a rebuild. After researching extensively about which engine to choose, I decided on the H23A VTEC. I planned on making the new engine run as an OBDII.
- I bought new: oil pump (H22 for crank sensor issue), timing belt, water pump, spark plugs, tensioners, spark plug wires, starter, rotor, distributor cap, oil pan gasket, front main seal, rear main seal, alternator belt, power steering belt, intake manifold gasket, motor mounts, headers and VTEC oil pressure sensor.
- We used from the old H22a4: fuel rail, injectors, dizzy, crank pulley (for power steering), and the throttle body (I believe).
The new engine is in the car and all hooked up. When my mechanic tried to fire it up, he said that he was getting a crank sensor error. He tested the sensor and said it was dead.
I bought a new crank sensor, and he put it in. Now, we aren't receiving any spark or fuel. My mechanic says that he can turn the fuel pump on manually with a scanner, so it's not the fuel pump or the main relay. Also, the coil in the distributor is new, so he ruled out the dizzy.
The check engine light comes on for 2 seconds, turns off, then stays on. In his opinion, my ecu was likely damaged in the flood and needs replacing.
I have a couple of options for replacing the ECU. I can go with a P13, P28, or P72. I ruled out the P28 since, from my understanding, they will not operate the IAB butterfly valves. That leaves either the P13 or P72.
In an effort to avoid potential problems with the demobilizer in my Prelude, I've decided on a chipped P13 - OBDI. I know I will also need the OBDII to OBDI conversion harness. From what I've read, the chipped OBDI P13 ECU should run my H23a VTEC with OBDII engine setup (dizzy, oil pump, etc) just fine.
- Can anyone confirm this information for me?
- Does anyone (that has the H23a VTEC) have any other suggestions as to the best choice for an ECU?
Also, I read on this thread something about having to switch the balancer belt pulley.
- Are they referring to the crank pulley, or something different?
This job has been the bane of my existence, seems like one problem after another. My car has been out of commission since late September, and I've spent something like $3k so far...I would GREATLY appreciate any advice or help you all can offer to get my lude back on the road as quickly and cheaply as possible.
THANKS!
