Pukki smashed home on the volley to equalise 11 minutes from time and Norwich should have claimed a massive three points in stoppage time when Martin Dubravka saved from Pierre Lees-Melou.
A point does little for either side's hopes of beating the drop as Leeds' 1-0 win over Crystal Palace moved them five points clear of the bottom three.
Newcastle are six points off safety in their bid to minimise the damage before they can turn to the Saudi sovereign wealth fund to strengthen in the January transfer window.
Howe was on the sideline as Newcastle boss at St James' Park for the first time, having missed the 3-3 draw with Brentford 10 days ago after testing positive for coronavirus.
The former Bournemouth boss could not have asked for a worse start to a crucial clash between the bottom two before kick-off when Clark inexplicably hauled down Pukki as he threatened to burst clear on goal.
"I felt the players showed real resilience, which we’re going to need for the upcoming matches," said Howe.
"If we can do that 11 against 11, we’re definitely going to win some matches."
No side has conceded more goals in the Premier League than Newcastle this season, but Norwich are also the lowest scorers and their lack of quality in the final third was obvious as they laboured to create chances despite dominating possession.
Newcastle looked to have snatched a first win under Saudi ownership when Billy Gilmour was penalised for handball inside his own box after a VAR review.
Tim Krul nearly denied his former club as he got a hand to Wilson's spot-kick, but saw the ball rebound in off the underside of the bar.
Norwich finally produced a moment of quality to ensure they remain just three points off safety.
Dimitris Giannoulis helped the ball back into the box after Dubravka flapped at a cross and Pukki smashed home a volley into the top corner.
Norwich then piled on the pressure in the closing stages, but failed to find the winner as Dubravka made amends for his part in the equaliser with a crucial late save.
Leeds gave themselves some breathing space from the bottom three by edging out Palace in stoppage time thanks to Raphinha's penalty.
Palace wasted the biggest chance of the game from open play when Christian Benteke headed Wilfried Zaha's pinpoint cross wide.
Leeds got the break their season needed deep into added time when Marc Guehi handled from Liam Cooper's header and Raphinha coolly slotted home the resulting spot-kick to move Marcelo Bielsa's men up to 15th.
