Honda Civic D15b no start[Solved] was created by Caritech
Hello all. A Honda Civic with a D15b engine hasn't started for 3 weeks. I have a few days to repair as usual.

-Spark is good (Igniter and coil replaced in distributor by mechanic)
-Injector pulse is present
-5v ref good
-Engine keeps flooding (plugs wet after crank)
-Oil smells like gas
-On clear flood mode it tries to start
-Mechanic reported timing and compression good
-Vehicle had no prior issue. It was parked on day and the other no start.

How's the spark plug condition, sir? I see that the igniter and coil have been changed, but are you still getting strong spark at the plugs?

What is your fuel pressure? Does it hold? If you disable the fuel pump, will it fire off of Starting fluid?

The plugs have decent spark. I didn't check fuel pressure yet and no it didn't start off fluid with pump off. One thing the customer mentioned is the main relay was inoperative and he soldered everything up and it started back working car still didn't start.

Good spark at the spark plugs. Check. Fuel. Check.

How's compression?

When Cranking, how does it sound?

Got to the shop late after the day job.
Fuel pressure was checked at the tank and showed a slight leak down.

No difference with ECT sensor unplugged.

Compression was 150 with throttle closed, cyl. 1.

No egr.

I was told mechanical timing was checked and was off but was "corrected."

Circumstances caused me lock off early but I have been thinking about something. The distributor has CKP, CYL and TDC pickups. Could it be possible for one of these to throw off ignition timing? An entire distributor couldn't be sourced so they changed igniter and coil because they reported no spark but when I got it on the site visit it had spark. The rest of the distributor was never changed. Will be getting a timing light tomorrow.

Update: Timing was off, belt was loose and a final compression check showed 40'ish psi across the board. Swapped a long block and Vtec kicking in again yow.
