It turns over, all the electrical seems to work, but it sounds like I'm getting no spark. I hate maintenance. Where should I look at this point?
fuel lines hooked up right ? wrong?
are you sure theres no spark?
no tight valves , I will assume no , since you just did them.
Its usually something you did reassembling . unplugged a harness etc etc
start back tracking your steps
Mustang's right, re-check everything you did first. Coil connectors in the right order that sort of thing, although if it sounds like it's not getting a spark it could just as easily be not getting fuel.
To check, listen for the fuel pump power up when you first turn the ign on after it's been standing a while. If it whines then stops you're getting something. Next, after winding the pump up, turn ign off and disconnect the fuel line. If you get a little spurt it indicates fuel pressure.
Check the voltage at your battery it's possible to have enough juice to turn the engine but not fire the injectors. Charge as necessary, in fact, charge it anyway as you've been churning it over trying to start it.
You shouldn't have needed to unplug the crank sensor, but did you? That would stop it also.
A few more ideas about what you did to check the valves might help us work out why it's not going. All we can do at this stage is list the things that will definitely stop it.
Didn't do anything with the crank sensor. The fuel pump is good. Everything is connected properly. Coil connectors are all loomed so they can't be put in the wrong order. Maintenance is unbelievably frustrating. I'm going to go through and clean up the contacts now.
You don't have the kickstand down or other safety switch issue?
Lol. Double checked that one.
Tested the battery. Double checked the connections. Fuel pump is good. I have no idea what to try now. All three coils wouldn't go bad at once, I don't think. The only thing changed was the spark plugs. I was so excited to go out for a ride.
Hey cba191 !! what about the clutch switch ??
and recheck yer kill switch :icon_redface: don't ask !!
good luck
KK
The kill switch was one of the first things I checked. And the clutch switch is good as well. I'm starting to think I may have to get it to the dealership and have them look at it. I hate that.
Check the fuses. Six and Seven feed volts to injectors AND coils and ECU. The ECU triggers the injectors and the coils by GROUNDING the live connection to them. If either fuse is dirty or blown, it's over.

That sounds promising. I'll check it tonight.
Unfortunately, the fuses are all good. Going to pull it apart again this weekend to check the gaps.
good move
because a tight valve on a intake with zero clearance will make it no start
Wouldn't it still start on one of the other two?
in theory , it should ...................have seen way too many that won't.
I'm still betting something simple stupid happened after the valve check during reassembly
I was referring to the gaps on the plugs. I rechecked the valves before I bit it back together. I measured after I put the new shims in.
Ok. I'm going to take it apart again. What are the things I should triple check and test? I know the clearances are good because I checked them all again before I put it back together. Everything else is suspect at this point.
start looking for pinched / removed vaccuum lines
are their more than one gas line? are they hooked back up correctly
There are two fuel lines. I think I connected them the same, but I didn't even know that could make a difference. The small hose with the big valve is on the inside. I'll double check the vacuum lines.
:nod
What about the main fuel lines. Do they need to go into specific outlets?
you wont get gas if they're wrong

I hope that's it.
Actually it doesn't really matter which way round they are as one feeds the fuel and pressurises the fuel rail (5 in Mustang's diagram) and the other bleeds off excess pressure. I suppose in theory the bigger one should be the feed. There are no one-way valves in the pipes or rail.
FINALLY!!!!!!!!
:hat10 :hat10 :hat10
Tweaks the gaps, fiddled a bit with wire management, and messed with the fuel lines a bit. I didn't do anything that seemed like a big deal, but it started right up.
Oil change tomorrow, LED headlight bulbs should be here Monday. Should be golden.
Weather permitting, I'll go for a ride tomorrow. :wheel
:thumbsup

Of course it'll pack up again just when you get somewhere without a mobile signal........

Sorry, can't quite catch that, you're a bit broken up :icon_mrgreen:
:ImaPoser
My guess (and it's only a guess) is that one of the hoses wasn't seated correctly and hadn't opened the stopvalve.
Actually, I think it was a problem with the spark. I pulled the plugs and connected them to the coils, and got no spark. Messed with the gaps and swore at stuff, and got them to spark. Reassembled everything and, voila! Did the 12 min thing and she's golden.
