First off this is my first post, I've been lurking for awhile and I love this community and everyone's vans! My dad just gave me his 1986 Van Wagon LE last month, and it had been overheating, and had been sitting for almost 2 years because of it. I ordered a headgasket, cleaned it up, pulled the engine apart, cleaned the old gunk and dirt out of it, and then patched it back up. I had a bit of a run in with vacuum and cooling hoses, but after hours and hours of work I finally got 99% of the hoses patched up with the correct diameter hoses. When I finally finished the job, I put a new battery in and I cranked the engine over. It turns without any resistance and the starter turns no problem. The thing just will not fire up. I can crank it for 10 seconds and then leave it for 30 minutes, try again, and no luck. I've purchased a spark tester and I'm getting spark on all 4 cylinders, I bought new plugs and wires just to replace the 20 year old ones that had been in there since the original owner bought the van, most likely. I made sure the metal fuel lines with the hollow bolts were lined up correctly, and just to check and see if there was fuel pressure I loosened one and cranked the motor, which made it super obvious that there was good fuel pressure when gas shot all over the place. I don't have any blocks in the intake, I'm fairly certain I don't have a vacuum leak, since I spent about 3 days making sure that all the vacuum lines were routed correctly. I'm at a loss here, and I can't figure out what could be wrong with it. Maybe you guys could give me some ideas? Any chance it could be electrical (any fuses I should check maybe)? I need to make this van run!

Also, when I was taking the engine apart I accidentally broke the old, brittle Engine Coolant Temp sensor (ECT) but I did some soldering and cleaning and tried to repair it the best I could. Could this be why the engine will crank and spark and get fuel but just won't run?
