In case someone needs rotor and spark plug wire alignments:

So I opened up the distributor's and found that I put the rotors on correctly. Bummer. I triple checked the spark plug setup too.

Now I need to verify electrical connections, voltages, ohm resistance, etc. Sucks when I know it was running poorly before and now that the timing is done right, I can't get it running.

Here are the pics of the timing marks on the LH/RH camshaft and crankshaft.

Does this look kosher to everyone? FYI, I also checked the electrical connections and found out that the ignition coils were out of tolerance when cold so I ordered new ones. I also checked the wires and found the resistance to be the same for the Left-hand and Right-hand side. If the timing and rotors are put on correctly and the spark plug wires are showing low for resistance, could it be just the ignition coils that's causing the start issues?

Thanks for any help.

Mike

Turn both the rotors around, as they should be facing this way.. Your cams are correct, just the rotors need to be turned 180*. With the cam position sensors bolted on the engine, when you turn the rotors around 180* you will see they are pointing right at a groove in the housing... I wouldn't order new coils as it was running before? they probably weren't being test correctly..

is it possible for one side to be off timing? ie, say driver side of the engine is off?

Thank you! I was so close to getting it towed and having a professional look at it. I ordered it anyways along with a new water pump.

I might as well as get in there while I'm replacing other things.

Thanks for your help again! I'll report when I get the parts and install it.

Very possible, I have heard after market belts are more prone to jump, but I don't know as I havent ever used one. Another possibility that who ever did the belt was a tooth off when they did your belt. I think there are a few different scenarios, but really it's tough to just guess.. as that is all I am done. One way to find out, take the timing covers off and have a look yourself, can't hurt.

Success! I'm so done with timing belt changes I think I'll take a break with my mom's car and mine(Lexus and VW) for a while.

Thanks for your help! Really appreciate it!
