TDC on the intake stroke ?
Posted on Nov 06, 2014
Testimonial: "Idk what exactly you mean... a beginner mechanic who did this job just off youtube videos was this guy.. I thought I had chain perfectly matched with sprockets and oil pump mark, and #1 piston up top... when i tried cranking it I got a backfire.. thinking jumped off time and ready to break it down again. but what did you mean tdc on intake stroke?? And thanks for any and all advice, this is getting frustrating.."

old fashioned method,no 1 pistonTDC remove rocker cover ,no 4 cyl valves on the rock and no 1 cyl open then look for some sort of landmark as i honestly cant remember where the marks should be.zetec the marks are on the back of the twin cams the grooves have to be horizontal with the rear caps remove the rocker cover and you will see it

I'm not sure what you may be "doing wrong", but here is the manufacturer procedure for aligning the timing marks.
^Refer to this diagram during step 12.
^Refer to this diagram during step 13.
^Refer to this diagram for step 19.
1. Align crankshaft sprocket timing mark to the mark on oil pump housing. NOTE: Lubricate timing chain and guides with engine oil before installation.
2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.
3. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
4. Loosely position left side camshaft sprocket over camshaft hub.
5. Align timing (plated) link to the crankshaft sprocket timing mark.
6. Position primary chain onto water pump drive sprocket.
7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.
8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
9. Install left side lower chain guide and tensioner arm. Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary.
10. Install chain guide access plug to left side cylinder head. Tighten plug to 20 Nm (15 ft. lbs.)
11. NOTE: To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.
12. Purge oil from timing chain tensioner using the following procedure:
a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
13. Reset timing chain tensioner using the following procedure:
a) Position cylinder plunger into the deeper end of Special Tool 8186.
b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
14. Install the reset chain tensioner into the right cylinder head.
15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
21. Install camshaft position sensor and connect electrical connector.
Hope this helps!

if you have disconected the battery for more than 15min then see if you have a reset on your fuel pump it would have run with the fuel already in the line
